Caching plugins are complicated beasts. They install a number of components that other plugins typically do not. You can’t just switch them off. For example, the uninstall routine for WP Super Cache is:

1. Turn off caching on the plugin settings page and clear the cache.
2. Deactivate the plugin on the plugins page.
3. Remove the WP_CACHE define from wp-config.php. It looks like define(
   ‘WP_CACHE’, true );
4. Remove the Super Cache mod_rewrite rules from your .htaccess file.
5. Remove the files wp-content/advanced-cache.php and
   wp-content/wp-cache-config.php
6. Remove the directory wp-content/cache/
7. Remove the directory wp-super-cache from your plugins directory.

My guess is that you have not completely uninstalled one or both of the plugins and are seeing the consequences. You need to go through the uninstall instructions for the caching plugins and make sure that you get everything cleaned up properly.
