Ошибка cannot open file for writing log

I have just uploaded my Joomla 3.1.1 installation from my development pc to my production linux server. The front end is looking fine, but I when I try to login as administrator, I get the message

0 Cannot open file for writing log

The webserver is Apache. I assume that this is a permissions issue, and have given the following folders 777 permissions:

logs
tmp
administrator/cache

The relevant lines from my configuration.php file are
public $tmp_path = ‘/tmp’;
public $log_path = ‘logs’;
(both as default)

What am I missing here?
Any help gratefully received
Miles

Thanks Barbara.
I sorted out the problem by deleting the configuration.php file, re-running the installation and then importing the data from a backup.

I found out that the error had been caused by the values assigned to the $log_path and $tmp_path variables — I had used a path relative to the web root and not absolute values.
Correct values were

$log_path = ‘/var/www/vhosts/mysite.com/subdomains/clients/httpdocs/Sacred/logs’;
$tmp_path = ‘/var/www/vhosts/mysite.com/subdomains/clients/httpdocs/Sacred/tmp’;

Many thanks for your help

My problem was that the «logs» directory was used by my hosting company, and I had no access to this directory.

I created a new directory called «binnacles», and changed the path in configuration.php to this directory:

public $log_path = ‘/homepages/2/d353530289/htdocs/binnacles’;

For those who face these issues:

To find out what your absolute path is, copy the following code into a text editor (i.e. JEdit, Notepad, etc), save the file as a .php naming it whatever you prefer (i.e anyfilename.php.).

<?php 
 $path = getcwd();
 echo "Your Absoluthe Path is: ";
 echo $path;
 ?>

Using your FTP software, ftp the file you have just created to your root folder.

Open your web browser and type in http://www.yourdomain.com/anyfilename.php. The result will show the absolute path!

IMPORTANT: For security reasons, delete this file as soon as you have ascertained the information you require.

Thanks leolam,

I moved my site to a new host and got the error mentioned above «0 Cannot open file for writing log». I used your absolute path code to find my new server’s path and was able to fix the path to my $log_path and $tmp_path in configuration.php. Thanks again.

The reason is some time your hosting providers log folder and the joomla log folder is same.
You cannot change permission hosting providers «logs» folder.

Alternatively you create the log folder example «joomlalogs» in joomla installed root path and set the permission 777.
After that set the log folders path in configuration.php example «public $log_path = ‘/www/homepages/htdocs/joomlalogs’;

Make it simple

I have same problem, when I try to update Joomla from 3.2.2 on 3.2.3

cannot open file for writing log

logs path and tmp path are good, I do not know what is wrong?

Hi ISScyborg,

did you solved your problem? I’ve the same problem too (trying to update from 2.3.2 to 2.3.3 —> look here) in the German area …

Ciao Arthur

leolam, you are the superstar.

Worked for me too — had not updated the configuration.php file correctly after a migration to a new host. Found the path using the code below and updated the configuration.php file. Job done.

Hey guys, i REALLY need your help!

i’m getting the same error message, already checked the paths (both of them), and the permissions! and still nothing.

buut, theres a few details. my host have the 3.10 php version and the joomla that i’m using needed 3.10.1. this is one academic website, so i can’t say to the manager update it, is not that easy.

so i re-write the configuration.php files (administrator too). the site is on http://labp2d.joinville.udesc.br

but when i try to log, that error pops out.

sorry about any «language mistake»

please, help me.

Hey,

I get the same error when I log in to my joomla website.

The last thing I did bevore I logged out was changing the eMail sending settings (smtp, account name and so on). Then I saved it. And logged out.

Next time I logged in the message occured.

Already tried changing the path (leolams idea). No success.

Some additional information that may be useful:

1. A friend hosts my site on his server. I started to build my joomla page on my own PC with xampp. I gave him the files and he managed it. It worked all fine until I was changing the settings (eMail sending and so on).

2. When I check the old directory of xampp (xampp/apps/joomla) and go in the tmp or log folder: there are No files. When I checked into the ftp folder where my site is hosted there are two files: /tmp/index.html and logs/index.html .

3. configuration.php : bevore I changed anything there (bevore leolams idea) there still were the old directories when I used joomla in xampp on my own PC (D:/xampp/apps/joomla/tmp or …/logs). But the site was working.

4. configuration.pho : there are no entries at all ftp entries ( public $ftp_host = »; …port, user, pass, root neither).

I would realy appreciate it if someone could help me in this case.

Thanks. Stinson.

Additional info I just found out that may be useful:

It seems that I cant change any permission of the original joomla folders or files.

Ask your friend to change configuration.php and put proper values in for $log and $tmp. It seems you are not allowed to do that.

Verify with System->System Information->Directory Permissions whether those folders are writable. They must be!

You could try to enable the FTP layer in Global Configuration. Your webserver doesn’t have write access to its filesystem. Provide the host/user/pw and try to save. When credentials are correct it should allow you to do that. This assumes you have FTP access to your webspace. Did you try with FileZilla?

Hi sovainfo!

Thanks for the reply!
——-
Important information about the problem: When I go to the login page http://www…..com/administrator/ and type in ANY combination of username and password and «Log in» it gets me to the page: Error — An Error occured — 0 Cannot open file for writing log (see attached picture).
———

I was able to change the configuration.php (and change the paths of tmp and log).

Verify with System->System Information->Directory Permissions whether those folders are writable. They must be!

Could you explain which directory to check and where (my Windows, Joomla (can’t get to System configuration), or with FileZilla?)? I guess you mean in Joomla.

I do have FTP (sftp) access to my webspace and I use FileZilla. «enable the FTP layer in Global Configuration» -> I can’t get access via the joomla interface. Is there a way to change it manually via FTP files?

Thanks for your help!

Stinson.

Edit: sorry for the link -.-

Update: Global Configuration = configuration.php
Changed following values:

public $ftp_host = ‘….com’;
public $ftp_port = ’22’;
public $ftp_user = ‘xxx’;
public $ftp_pass = ‘xxx’;
public $ftp_root = ‘/var/www/xxx/’;
public $ftp_enable = ‘1’;

xxx -> just for the forum of course.

Result: Now when I log in it takes longer to load but I get the same error page.

Hi, getting the same problems like others above on one of the test server:

Cannot open file for writing log

When I changed the log folder to 777, everything is OK, so this seems to be permissions problem not the path problem.

The problem is, the site is working with FTP layer and it works OK

When I look at:

librariesjoomlalogloggerformattedtext.php

I see:

if (!$this->file = fopen($this->path, 'a'))
		{
			throw new RuntimeException('Cannot open file for writing log');
		}
		if ($head)
		{
			if (!fwrite($this->file, $head))
			{
				throw new RuntimeException('Cannot fput file for log');
			}
		}

Which seems to be not compatible with FTP layer (no JFile, no JFolder, etc. )

Can somebody confirm this?

Thank you, Jan

For those who need to write Log entries with FTP layer
(be aware, writing files and their content with FTP layer takes more memory resources than not using FTP layer)

EDIT:
librariesjoomlalogloggerformattedtext.php

method:
public function addEntry(JLogEntry $entry)
http://www.phoca.cz/joomla/api/class-JL … #_addEntry

FROM:

if (!fwrite($this->file, $line . "n"))
		{
			throw new RuntimeException('Cannot write to log file.');
		}

TO:

jimport('joomla.filesystem.file');// can be set in header
$content = '';
		if (JFile::exists($this->file)) {
			$content = file_get_contents($this->file);
		}
		$content = $content . $line . "n";
		if (!JFile::write($this->file, $content)) {
			throw new RuntimeException('Cannot write file for log');
		}

I have this same problem but it didn’t help when I created a new folder and changed my configuration.php file. I am trying to update from 2.5.28 to 3.4 and it fails every time. The error says that it cannot open /logs/index.html because it is not writable. For some reason, Joomla keeps looking for that file (which doesn’t exist) and I can’t seem to change it! The site is on 1and1 and they have that logs folder locked down so I can’t do anything with it.

Any help would be greatly appreciated!

I’m migrating my joomla 3.3.6 project from local to online server, but I get this error when I try to login into my administrator panel:

Error: 0 Cannot open file for writing log

My tmp and logs paths are correct in my configuration.php, and the permissions of the folders and files are correct too (755 and 644).

I don’t know what else to do.

This worked for me:

Check path of your application, by

<?php
   $path = getcwd();
   echo "Your Absolute Path is:" . $path;
?>  

then set

$log_path = 'Your Absolute Path'/logs

If it does not solve issue, then

First check in ssh who owns the /var/www directory by:

ls -la /var

Then check what user apache uses

ps aux | grep apache

or you can use:

ps aux | grep http

output:

apache   29672  0.0  1.3 388232 14240
root     29679  0.0  0.2 110456  2252  

in my case apache user for /var/www was apache

so after this I made apache the owner of /var/www by:

sudo chown -R apache /var/www
