Help: I get a blank page

[cirdok2]

I upgraded from 3.0.7 to 3.6 (reverted all the templates) and everything seemed to go well.

Suddendly I got a white blank page and I am not able to load the forum.

The admincp works, I tried to rebuild the languages and I got this error:

Database error in vBulletin 3.6.0:
Invalid SQL:
LOCK TABLES mailqueue WRITE;
MySQL Error  : Access denied for user 'xxxxxx'@'localhost' to database 'xxxxxx'
Error Number : 1044
Date         : Sunday, August 13th 2006 @ 08:03:38 AM

Any help, thanks

Look like your user does not have the write privliage for your database.

Look like your user does not have the write privliage for your database.

I have done all the installation with that user and everything went fine for many hours.

Suddendly I got this blank page:

I have also an adserver in mySQL, same user and it works fine.
But in vBulletin I got that message also if I go in Style Manager.

Have I to ask to check to my hosting?
Thanks

The most likely cause of this error is that the info in your config.php file is wrong or your db user does not have full permissions to this database. Please read this for all the known causes of this error:

If the error you are getting also includes this section:

Invalid SQL:
LOCK TABLES ......

Then you need to make sure the DB user has LOCK permissions to this database.

but how can it happen suddendly after 2 hours I was working, browsing and inserting thread in the forum?

After deleting a message I got the blank page and errors dispatched to my email (but I had already deleted some posts before and everything was ok).

I checked the config.php files and it is ok.

Is there any test I can do, or I have only to wait for my hosting to check the database?

Thanks guys, I really appreciate your help.

If you are getting the 'access denied' error, then those are all the known causes of that error.

solved enabling lock grant... thanks guys and thanks also to my hosting, very helpful also on a mid-August Sunday

[cirdok2]

After enabling lock table grants, everything look fine.
I also repaired and optimized the tables.

Is there anything else I can do (besides go to sleep)?

Thanks

If things are working, take a break.
