New error

I have had an installation on my webpage - evrything was working fine. Suddenly there’s a lot of errors like this:

SQLSTATE[42000]: Syntax error or access violation: 1044 Access denied for user …

No change in user information - all values in config OK. What is happening??

please grand LOCK privilege to your SQL user as it is now a new requirement

I’m not in control of the priviliges set for this system user. Is there any other way to tackle it??
