I have pretty hard problems with time outs, errors, log outs etc. since such a long time.
Its more than boring.
I use firefox and I suppose such a forum should work with this browser properly.
I remember someone thought firefox might cause that isssues.
BUT a worldwide used browser can NOT be the reason if a website is working so lousy.
We had such kind of errors in the past, it was getting better for a while,
but now the whole … (censored) is the same,.
It was me that stated that my good man.
I get a lot of these that you state and another one or two when I try to post something that ends up in duplicate postings.
There is like another or so that I found and not listed here. Those are mentioned to admins already
So we wait, wait, wait!
There are some problems using Chrome as well
OK we know, the admins know.
What will happen?
We know 
Chewing gum!
MUST be the next theme for the photos! 
BTW Brenda Lee is fantastic!
Such a great song!
I’ve been having some timeouts recently myself.
