Thread:Project:Support desk/HTTP 500 problem when trying to access mediawiki

I use mediawiki through a "bitnami stack" Recently I have been trying to use an old archive of my mysql data from 2014 with the new install of mediawiki (version 1.24.1.0).

I installed everything and the virgin installation is working fine.

As soon as I replace the virgin mysql/data folder with my folder from 2014 (as well as updating the LocalSettings.php, I get HTTP 500 Internal Server Error page. I can see it trying to do "Login Required...", "Waiting..." steps before failing.

Also, it updates the date modified of the following files in mysql/data: ibdata1,ib_logfile1 and ib_logfile0.

I don't see any obvious errors in apache error logs and nothing is written to mysql error log.

What is the best way to trouble shoot this? I do not understand how mediawiki works but I can run commandline commands and look inside files, etc.
