XF 1.3 Need Help An unexpected error occurred. Please try again later

#1
The website was fine yesterday then all of a sudden we get this unexpected error, I can access the FTP and server but unsure how to address this, I can't access the forums or admin panel.

Any help would be greatly appreciated.

Thanks.

The actual error is embedded into the HTML:

HTML:
<!-- Mysqli statement execute error : Incorrect arguments to mysqld_stmt_execute -->
That's one for your host to sort out, I believe.

This may be the same thing I saw Mike mention earlier. Are you hosted by 1&1, by any chance?

It seems as though they've changed something and effectively broken everyone's MySQL servers.

Yes, as Chris said we have had numerous reports of it today.

Your host has made a change which needs to be rolled back or you need to choose the PHP 5.5 option in your control panel.
