I've tried contacting the mods about the faults but nothing as yet has been done about it.
I have been looking into this for you today, Luke, as I said I would when replying to your PMs. As I've let you know, I've so far found nothing in your account that should affect site performance for you.
Site traffic has also remained consistent, and members seem to be posting normally today, so if there is a problem with the site at the moment, it's rather difficult to pinpoint.
We'll endeavour to keep looking, and I've suggested some other things in our exchanges that may help, but from the information at hand there is a likelihood that the problem isn't on the site itself. It seems a good sign that you've been able to make some posts this evening. Here's hoping.
