SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM `wp_posts` p LEFT JOIN `wp_post2cat` pc ON p.ID = pc.post_id LEFT JOIN `wp_categories` c ON pc.category_id = c.cat_ID WHERE post_status = 'publish' GROUP BY cat_ID

you have an old, out of date plugin (not spf)… the wp post2cat table hasnt existed for some time now in wordpress…
you need to find which plugin is trying to access the non existent table…

spf is not doing anything – its the invalid plugin…

figure out which plugin has not been updated to work with wp 2.1 … that table has been gone for a long time now… the plugin has likely been updated to work with your version of wp… you cant trust the plugin page to show you which ones need updating because it only shows you for plugins hosted at wordpress.org…

easist way to find out which plugin is at fault here, is to deactivate all of them except for simple press. your site will most likley function properly now… then start activating your plugins one by one until it starts breaking… then you know the plugin at fault and can check for an update or another one that is current and does the same thing…

its also possible your theme is at fault (maybe search the theme files for the invalid table), but less likley…
