XF 1.5 Mysqli errors that started this morning

[Thomas Vollath]

I haven't done any updates or other changes to the website in many weeks, but this morning when trying to access http://ftog.net I am getting these errors:

An exception occurred: Mysqli statement execute error : Incorrect arguments to mysqld_stmt_execute in /homepages/14/d168598602/htdocs/ftog_xenforo/library/Zend/Db/Statement/Mysqli.php on line 214

I have no idea where to even start trying to fix this and I would appreciate any help I could get from the community. I have source code and PHPMyAdmin access to the database so I can run queries if needed.
