We're still investigating issues involving pages that give you oops errors since the cloud server changes and we do think we've made some progress. Right now when you visit your forum posting history you shouldn't encounter an oops error anymore. Further investigation is being made for other areas.
When you load up a topic that has too many pages to load , you may notice that you'll encounter an oops error. When a user loads a page, the way the forum code was set up they're loading data for the entire topic.
If you think about this, we're loading tons of megabytes based on people's avatars, signatures, but what about the screenshots or other fun images? Disallowing game screenshots and entertainment images in topics is not an option, so we're implementing a rule set that disallows signatures over 1MB. If this precaution doesn't help, we may disallow animated .gifs in signatures until the site is rebuilt. We'll follow-up if there's any changes to reflect this.
Also, if you notice a warning mark, this is for the purpose of sharing why your signature was removed, which will not negatively reflect your moderation history
Thanks for your continued patience.
