The site has been having issues which will hopefully be fixed soon. They are working on it.

"As per our discussion earlier a while ago, you have opted into the PHP 8 migration for your vBulletin forum. It is the proper time now as I've also been planning to do a full reinstallation due to the recent sabotage/hacking incident on the site, therefore it is also good to start this process."

Thanks for the update. Looking forward to the fix to improve the speed on the forum!
