In your 3.8.4 upgrade folder, includes/config.php, insert the following directly under <?php:

define('DISABLE_HOOKS', true);

This will force all add-ons to be turned off.

Now you can enter your test forum's AdminCP. Go there, then Plugins and Products on the left side near the bottom, and select Manage Products. Uninstall everything.

Now go to Plugins and Products -> Plugin Manager and uncheck anything that remains. Click Save Active Status to turn them off. Now you can go back to this screen and delete these with the Delete link on the right side.

At this point, you should be able to navigate around your upgraded forum with only default vBulletin code running. If everything's satisfactory, remove the Disable Hooks line you inserted into config.php earlier, and double-check the forum.

Once you're satisfied with your test forum, you're ready to upgrade your live one! :up:
