Hello!

Try to clean `Modules` table of ur Dolphin - may be it will help. If not - then provide me via PM access details to ur site.

Regards

Thanks LeonidS for the reply. The modules table is empty.

Hi given below is the front end error message and emailed debug:
repairing temp folder and increasing mysql time limit from hosting provider did not work.
Most of the time the error report is almost similar except change in called script= "where user gets error" e.g 
Called script: /blogs.php
Called script: /index.php
Called script: /blogs.php
It is not a permanent error, it starts any time daily for a few minutes to as long as 45 minutes and all users trying to access any page of the site get error  during which several times the error is shown on the front end (which of course get logged into error log of server and emailed to me)
please save me
Thanks
