Go into phpMyAdmin (http://www.simplemachines.org/community/index.php?topic=21919.0) and click on your database. Then click on the SQL tab and copy paste the following code and run it:

INSERT INTO smf_settings VALUES ('disableTemplateEval', 1);

Use the forum a little and try to regenerate new errors. If any are found, post the new ones here. Then run this query to undo the change we made earlier:

DELETE FROM smf_settings WHERE variable = 'disableTemplateEval';
