WHMCS Error

Hello. I have an error with WHMCS and i am unable to login to my admin control panel. Here is the issue that i have been told is wrong by WHMCS: Hello, An internal server error can be a lot of things but it's almost always a server issue - not WHMCS. It could be that ioncube is incorrectly installed or there are some settings in a .htaccess file causing an error. Here are a few broad areas for you to check in order to resolve the issue: An error in one of the PHP Files - Try enabling the display errors option. Please ensure display_errors is enabled in the server's PHP configuration and then enable in Setup > General Settings > Other tab > Display Errors option, then reproduce the problem. File Permissions & Ownership - All files should have a permission level of 644, folders should be 755. PHP Memory & Process limitations - Try increasing to 128MB PHP Process Limitations - Check with server admin/hosting provider Corrupt PHP Modules, Extensions, Builds - Check with server admin/hosting provider The obscure - If points 1-5 don't produce a fix typically the best course of action is to check the Apache Error Logs. If the error is not displayed when following point 1, the error is beyond the control of the WHMCS Installation & staff as it becomes a Server issue, which we would not have the level of access to completely resolve. Examining the Apache Error logs is the next step in trouble shooting, which depending on your level of access, may require contacting your Hosting Provider to assist. Looking for someone to do this for $20.
