XF 1.2 How to disable an add-on without admin access


Well-known member
I've upgraded* to 1.2 and was slowly activating add-ons and checking my forums to see which ones work okay. One of them when I enabled it prevented me from viewing the forum and admin control panel.

How can I disable this add-on (Or others in the future) without using the admin control panel please?

* I did create a backup of all files and the database before upgrading :)
