How to fix Joomla error Incorrect key file for table ‘jos_session’; try to repair it

Re: Error: Incorrect key file for table ‘jos_session’; try to repair it

The fact that you’ve got this error means that you are running Joomla 1.5x, under mysql4.x and have just upgraded to mysql 5.x probably without backing up your database – am I right?

Ok, don’t worry, there is a fix. First, the problem is that mysql 4.x and Joomla 1.5 use incompatible indexing with mysql 5.x, so the upgrade would have probably updated all of your tables except for these specific Joomla files. We need to delete the old Joomla table and rebuild it.

You need to login to Plesk and find the client account with the problem, log in to phpMyAdmin and apply the fix below by running the SQL as follows:

Do this for each corrupt database. Your Joomla application will start running straight away!

PHP 5.3 and Zend Optimizer

Ok, so you are running PHP 5.1x / 5.2x and need to upgrade to PHP 5.3x in order to support the lastest WordPress 3.x incarnations, but you have a problem – you also have Zend Optimizer (module php-zend-optimizer) installed, there is no support for the standard Zend Optimizer in PHP 5.3x (or later).

Never fear, you can resolve the problem like this in Plesk:

# yum remove php-zend-optimizer

Now you can upgrade php (using the atomic repository), as such:

#yum upgrade php

Now you should install the replacement for Zend Optimizer as follows:

yum install php-zend-guard-loader

Restart apache:

# service httpd graceful

Job done!

phpMyAdmin Export Database Error /domains/databases/phpMyAdmin/export.php

Trying to export a database but getting the error “No web page was found for the web address: “https://server.domain.com:8443/domains/databases/phpMyAdmin/export.php”

Given that error message, you’d be excused for thinking that the file export.php was missing or your pypMyAdmin installation was messed up – but you’d be wrong!

This error is not intuitive, the file export.php is actually there, the problem is this.

  1. Your database is on the large side
  2. Your php memory limit is set too low

To fix, simply increase your memory_limit as follows:

# vi /etc/php.ini

Find the line that says “memory limit = (some)mb”

Change the value to something considerably bigger, usually 512mb will do the trick.

For example:

memory_limit = 128M      ; Maximum amount of memory a script may consume

You will now be able to export your mysql database without further ado.

How to disable Plesk open_basedir restriction in effect

Some applications require open_basedir to be “loosened” a little, if you are installing an application such as ClickCart Pro then the open_basedir will need to be changed so that the installation can create the required sub directories and then complete.

Let’s assume your domain name is domain.com (no such luck, I know!)

# vi /var/www/vhosts/domain.com/vhost.conf

Add the following lines:

<Directory /var/www/vhosts/domain.com/httpdocs>
php_admin_value open_basedir “/var/www/vhosts/domain.com”
php_admin_flag safe_mode off
</Directory>

Now we need to rebuild the apache configuration:

# /usr/local/psa/admin/sbin/websrvmng -u –vhost-name=domain.com

Job done, your open_basdir setting has been moved up one level (from /httpdocs to /) within your domain name sub folder.

WordPress upgrade fails, “Could not copy file: /var/www/wordpress/wp-activate.php”

Have you logged into WordPress and you get the message “WordPress update available, click here to upgrade”, you click “here”, wait and then the upgrade fails?

This is a common problem so we would like to post the solution for our clients:

1) Ensure that your FTP user is the owner of your WordPress install directory, this is most likely not the problem unless you have your own dedicated server and installed WordPress using root user.

2) Ensure that your WordPress directory has the correct permissions, it should be 755. This is the most probable problem. Change the permissions to 755 and then try the WordPress upgrade again.

If your FTP user is not the owner of your WordPress directory OR your WordPress directory has permissions other than 755, your WordPress install/upgrade will fail with the message “Could not copy file: /var/www/wordpress/wp-activate.php”.
