When I tried to view first page of Bug reports forums, I got following error message: An error occured with your last action. Please reload or contact an administrator if this error persists.

I tried to close/reopen browser, and/or using InPrivate mode, but nothing helps.

This happens only first page; second page and after that, I could read contents normally.

Try Ctrl+F5

Unfortunely, Ctrl+F5 didn't resolve this issue.

I had the same error message but only on page 2 of this forum. It was with chrome. Everything else was good...

I try with Edge and Firefox : it was OK.

I try Crtl+F5 (to force reload the page) with Chrome : always the same error message...

Finally, I cleaned up the Chrome cache and it was good!

UPDATE: 

Currently, page 1 is displayed correctly. However, page 2 is broken as same manner.

I think there are some threads/posts that caused this issue in Bug reports forum...

Thank you for bringing this up. It should be fixed now.
