We moved hosts last week, so I changed the wp-config file to the new database details and all was ok.
We can view the blog, add articles etc, but then sometimes we just get a database error and we can't view the blog at all or use the preview function. This error only happens once in a while, but it's a bit frustrating. Is there anything that could be causing this? Plugins maybe?
Error message: Connect failed: Access denied for user 'USERNAME' to database 'DB_NAME'
The username and database name shown in the error message are the OLD details, suggesting these are still in existence somewhere.
Thanks in advance
