I can no longer post under my usual username - Supahoopsa (hence registering under this new name in order to create this thread).

I just get an error saying I cannot create posts.

When I try to see my forum posts I get this error (this happens with my old username and my new one!!!!)

A critical error has occurred.
Object reference not set to an instance of an object.

Anyone any ideas as to what is going on today?

I am now using my SupaHoopsa USername and I have gone to my forum settings and checked that I don't have any forums being tracked and I also clicked on the "Clear Read Status" option. I can;t see any other options to clear out notifications - I know I have subscribed to a number of threads (not that it is any use because I NEVER receive email notifications, but that is another story!)

I can reply to threads, but I still can't access "My  Posts".

If I try creating a new thread I get the following error:

Add/Edit Post

I have the same problem like SupaHoopsa. 

In MySettings/Tracking subscriptions, all are unticked. However, I still can't post new thread. T_T
