Joomla Extension Manager issue - Getting an HTTP 500 Server error

Question

I am using Joomla on my website. Now when i try to access the Extension Manager under Extensions, it gives me the following server error

The website encountered an error while retrieving 
http://myURL/upload/administrator/index.php?option=com_installer. 
It may be down for maintenance or configured incorrectly.

How do i fix it?

Thanks

Answer 1

You should definitely find more information in the error log, but a few things to look at are:

1. permissions: com_installer may need the tmp folder to be writable
2. configuration: is your tmp folder configured properly (you can check in system information)
3. corruption: try reinstalling the update package of Joomla over your current installation (the update package) with ftp/shell
4. improper routing configuration: you may have some wrong configuration either in your httpd.conf or .htaccess file (try renaming them quickly to see if this is the issue; look for an .htaccess in the administrator folder, and each parent up to the web root (so ./uploads/administrator, ./uploads, . )

I repeat, reading the error log (apache error_log or php error, or turn on debug in Joomla) should give you more than enough information to pinpoint the issue.

I had the same issue when I had forgotten to rename htaccess.txt to .htaccess
