When you post, please make sure the thread title starts with "Opera Mail - " so that my Thunderbird RSS feed saved search (named "M2 Forum") catches your post.
I posted in this forum in response to the first poster. I thought it might help to know others had seen the same error.
The OP seemed to be talking about this forum so if the problem is with other forums then it should be reported elsewhere once it may be an Opera issue and not a forum one.
