I recently tried to make a new wiki called the "Vaporwave Samples Wiki". In the final step of the creation process, it said "creating wiki", but the loading circle kept spinning, and there was a message on the top of the screen that said something along the lines of "Oops, there's a problem on our end". After like 15 minutes of waiting, I decided to just exit the tab, and try again to see if that would fix it. When I tried to create it a second time, it said that the wiki already existed, and linked it. When I went to the link, it was just a blank screen with the text "[046bfd14c2e56a0057c0f6ef] 2020-07-05 22:24:45: Fatal exception of type Wikimedia\Rdbms\DBQueryError" with the random text at the start, and date changing whenever I try to access it (note that this is not what happens when you type in the link for a wiki that doesn't exist). The same thing happens on both my laptop, and phone, so I don't think it's on my side, and a Google search of the issue yields no useful results. I waited a few days in the hope that it would sort itself out on its own, but the problem persists. If nothing else, I can just try to make the wiki again with a different url, but I figured I post here first to see if anyone knows how to fix this.
Here's the link: http://vaporwave-samples.fandom.com/
(sorry if this is the wrong board, I wasn't really sure where to post it)
Edit: By the way, the browser that I am using is Google Chrome, but I tried it on Firefox too, to no avail. Also, the tab is named "Internal Error - Vaporwave Samples Wiki"
