While I’m skeptical there are many people still using fedia.io, I have been continue to try to fix the error 500 problems. These errors are caused by kbin thinking it stored database records with pointers to images (like the avatar image, images attached to posts and the like) but not actually finishing. So when certain records are pulled up (magazines or posts or users) where there is a missing image record, an error 500 exists. I’ve continued to find more instances of this and frankly I don’t know what is causing the problem. As a mitigation, I have been running cron jobs every 15 minutes to correct these broken links. This morning, I believe I chased down the cause of the last remaining disconnect and have that being fixed as well.
I suspect there are still other problems, like replies appearing twice. I will try to figure out what is going on with those as I can.
Extra points for perseverance to you!
