Error while trying to access forum

When I try to access the forum, I sometimes get the following error
Page could not be loaded
The requested page could not be loaded.
Check your internet connection and try again.
Certain browser extensions, such as ad blockers, may block pages unexpectedly. Disable these and try again.
Referral Index Forum may be temporarily unavailable. Please check back later.

Is there a problem with my browser or internet connection?

It happens but not that often to me personally too. Just try again later.

The forum was originally set up with a message that appears from having an ad blocker enabled. However, I removed that feature earlier today.

Clear your browser cache and cookies, and this shouldn't be an issue for you anymore.
