An email gets dispatched every time a database error occurs, so in these cases my email account gets literally flooded with those mails. Hence, I do know about these errors, but in this case there's not much I can do about it. I'll get in touch with the hosting company, if these errors persist. :shrug:

Do you think then that it's a coincidence that these error messages started appearing only after the install of the new software?

They have been there before.

I started getting them after the install but then I am using firefox only recently...so I am getting all kinds of errors I didn't have before...

Coincidence.

Must be...

The other night they kept coming up every five minutes and telling me that the server was too busy and I should come back later !!
