Thank you Olga
That matches what I’m seeing too. I’ve tried my hosting provider again but they aren’t keen to help further so I’m trying a work around whereby I’ve created a number of database users with the same password and each time a query is made it uses a different user at random. That way I’m hoping to increase the 75,000 limit enough for it not to be a problem. I can’t help thinking that it may be a problem with the way their database is set up as initially it was causing a couple of my websites to go to the initial install screen (both websites were using the same database username/password combination despite being separate databases). I changed these to different usernames and that restricted the impact to the one site based upon your theme.
Anyway hopefully this change to the wp-config file will sort the issue for now.
Many helps for your support, as always it is excellent from 8Theme!
