MySQL Error - Exhibition Groups

[stevemul]

EE Database has worked well for 9 months but now I get an error. I cannot modify Exhibition Grouping. Whenever I hit the button "Save This Group" I get the following error :-

Exhibit Engine MySQL error!
ERROR FROM QUERY lock_groups in page 'exhibition_group_editor':

------------------------------
Access denied for user: 'admin_ee@localhost' to database 'e_engine'


I can add a new grouping manually using phpMyAdmin but can not do anything from EE.

Any ideas would be very much appreciated.

Thanks,

Turns out this was a problem with my ISP. Some MySQL privilege was changed on the server. They have not given me any more details so unfortunately I can't enlighten the readers of this forum any further than that.

It's good to be able to report back that there is no problem with EE.
