We’ve seen sometimes that when we log into the Joomla administrator section we suddenly get the error “500 – An error has occurred”. However the frontend of the website is working fine.
To fix the issue above check the follow things with your webfiles :-
Step 1: Check the log directory path inside the configuration.php file and if it is not correctly set up then correct this and save the file and then recheck it.
Step 2: Similarily, check the tmp directory path inside the configuration.php file and if it is not correctly setup then correct it and save the file and then recheck it.
Step 3: Check permissions on both the log and tmp directories and they should be writable by the web user as well and if not then grant the permissions and then try again to log into the admin section and this will fix the issue for you.
That’s all.
