I read that page five times in the past two days. But DrByte inspired me to go back to the log directory to see what's going on. Hmm, no new logs, despite the errors. Then went to the admin, only to realize after updating my database for 1.5.1 it pulled in the old log directory location. After updating the location got to the logs and found:
Code:
PHP Fatal error:  1054:Unknown column 'pages_meta_title' in 'field list' :: select pages_meta_title, pages_meta_keywords, pages_meta_description FROM zen_ezpages WHERE pages_id = 6 in /html/includes/classes/db/mysql/query_factory.php on line 120
So it wasn't this mod and in fact it was EZ-Pages Meta Tag Fields causing the error. Reinstalled the SQL and EZ Pages are back!

HOWEVER, that doesn't change the fact that the Install/Uninstall Multi-Language EZ-Pages option is still not showing up in the admin>tools, and now I hope I didn't screw anything up by running the file directly (uninstalled, reinstalled, then fixed).
