Just moved my forum from one domain to another one. Have migrated it well, worked nicely. Then I remembered my sitemap plugin was generating 10K files and the developer released an upgrade that helps with this. So I upgraded the plugin. Then, when the cache rebuilding started, it all went crazy. The main forum page is WHITE. I have tried adding a line of code that would give ideas of what's wrong. It doesn't work. Have then read here about the possibility to rebuild the master data. I can't do it. For the past hour I've run this for nothing. It 'hangs' on phrases then generates a 500 internal server error. I have uploaded and re-uploaded all files few times already, checked them to see how they look. All seems fine to me. Don't know what can cause it and how to re-gain control of the forum. Any help is much appreciated. I can send the cpanel/FTP details via PM to whom is willing to help. Thank you in advance.
