core update crashes
Installation and Configuration
If you're getting 500 errors on your system, and it's all related to files not found, then there is a reason that is happening: Either the files do not exist, or they exist in a different location than your website is configured to look.
Again - in either situation a competent system administrator would figure it out very quickly. I understand you're annoyed and want this to be a Jamroom issue, but it's not.
