Arighty i am currently in the process of diagnosing an issue with the forums so we will have a small loss of some functions for a little while, the forums should still work fine its just that a few minor functions things will be down for a little while. Generally speaking you wont have any issues making and reading posts and most people should not notice any loss in functionality while i am diagnosing the issue.
Tapatalk being disabled has to do with me trying to diagnose the issue - i have disabled all plugins for the time being, ill put them up again very soon as it appears plugins are not the issue here.
Question though : how long have you not been able to use tapatalk ?
You know i was thinking that, forget about patching up this issue and just focus on getting v4 up and running with a nice new fresh install of the forums.
