Forum malfunction ?

A few days ago I got a PHP erreor while trying to access the forums...Then onwards, I received no emails of PMs, or replies to my posts. I checked my profiles...All fine... But I still do not receive any message about replies to my subscribed topic...

Please do something about it....

And now I am receiving the mails a few days after replies are given to my posts.

Is this a electro-tech error? my gmail account is receiving other mails in minutes.
