Problem: XMAP displays a blank screen when you click on the sitemap in Joomla 3.2.* and higher, or it displays a Internal 500 error.
Solution: XMAP references a component that is no longer required in versions later than 3.2.*
Remove or comment out the following line from /components/com_xmap/helpers/xmap.php
REMOVE OR COMMENT OUT: require_once(JPATH_SITE .’/includes/application.php’);
It should be in the top 7 lines of the php script.
SYMPTOMS: You are trying to install a plugin or component using the extension manager in Joomla 1.5 or higher and receive JFolder::create: Infinite loop detected
SOLUTION: Your TMP directory is not set correctly. In many server configurations open_basedir is set to a specific folder in your php.ini settings. Try changing the tmp directory path from /var/www/yoursite/httpdocs/tmp to just /tmp in the Joomla global configuration.
Symptoms: Joomla 2.5.8 hangs during installing at Step 1, the language install. The screen displays a circle that spins endlessly.
Solution: base directory rewrites are not enabled, rename htaccess.txt to .htaccess, refresh the page.
Symptom: What is the proper permissions for Joomla’s configuration.php?
Solution: The proper setting is 0644
owner: read and write permissions,
group: only read permissions,
others: only read permissions.
To change from SSH/Telnet: chmod 644 configuration.php
Always check the configuration.php permissions after a fresh install as some servers require it to be set to 777 prior to completing the configuration.
