Once and IF we get the server(s) back up and running, they need to be listed on the Wiki in a particular order, so I can remember the which server is which when I try to login. *It's a mental memory thing*
I believe the wiki software needs to be upgraded, the issue sounds like it is due to mediawiki upgrading to a newer version pcre (Perl Compatible Regular Expressions, I had to look that up ) based on the fact that if you click on the "view source" button all the content is still there, so its a display error rather than anything else. I have no experience with mediawiki but if i can help then let me know (although I would assume the owner would need to do it rather than an moderator)
I have attempted contacting the new owner of the company, the old owner of the company. I've posted support tickets, posted in the moderators section. It is like a desert. No signs of life what-so-ever.
