'We' have got a bit too used to 'server errors' over the last few months.
'Obvious answer' was to move server, especially when things got worse and it became impossible to register new users!!!
But.
One problem is that since CCE started, the software (bbPress) has become 'just' a plug-in of WordPress. That may have to be dealt with in the future.
Several CCEers have been offering advice and looking at alternative hosting and also forum software.
For now the software remains the same but the server changed late last night - facilitated by chrisfl. Probably fewer 'server errors' but also opportunities for small improvements - particularly the registration of new members! The last ISP changed their version of php which (somehow or other) disabled various bits of CCE. New server has 'better' version of php (or people that understand things better!)
One consequence was that the simple 'are you a robot' test didn't defeat some overnight Chinese spammers, who seem to have moved on from trainers and jewelry to wedding stuff.
