I'm getting the following error when I run the component:
Fatal error: Maximum execution time of 120 seconds exceeded in /home/xxxxxxxx/xxxxxxxx/xxxxxxxx/libraries/joomla/utilities/simplexml.php on line 440
Does anyone knows what it could be?
Yeah, go into the parameters and set "Find Version" to "No". When that's set to Yes, if a file has been modified, it will try to see if that file belonged to an earlier version of Joomla (missed because of a partial upgrade, possibly).
We threw it together quickly to get some ideas out there on how security can be better performed as a component. While we try to increase your memory and timeout limit if Find Version is set to Yes, many server installations don't let the script do this themselves.
A future update will do it differently, either through AJAX call or a more streamlined (less intensive) process for finding different versions.
