Stupidoo!!!

I had this error message: [an error occurred while processing this directive] while I tried to access my homepage, which was an issue I thought I took care of long time ago. I thought I changed some .htaccess content before for security reasons, so I was trying to figure out what I did wrong with it. It took me some time but I finally found this page and reset my file permission of index.php to 644 and it started working. Strange, though…who changed the file permission? Me?
