We moved hosts and after updating the nameserver on the domain, some users are reporting a blank page either directly at the /index.php or after sign in. if they clear cookies/cache, they usually get to the front page, but after trying to sign in, they are directed to blank page.
This seems to be plaguing about 50-70% of our users, and I'm trying my darn hardest to repro it from my side but the site works like a dream for me.
Unfortunately I don't get the blank page, but I will ask some of my users to check.
I will also disable add ons.
Meanwhile, I found another issue that may or may not be related.
Some of the forums posts are not loading as normal. They are showing in the forums list, but when you open the discussion, the discussion in blank and there are no posts visible.
I most certainly could do that, but honestly the support at my host is not the best.
Sounds like an error from xenforo end though. Probably something from the way I transferred the files and databases, I'm thinking something went wrong there..
DNS not resolving is definitely not an application issue, but your example shows you loading "ww" not "www" so that's probably the issue there.
Otherwise, these errors look like a bad transfer of files and potentially the database as well. While you can reupload the files, if the backup/restore wasn't 100% complete (which might explain the missing posts), that can only be resolved by going through the process again.
