You can not install Tapatalk through the auto mods tab. The mobiquio folder goes into your root directory.
that's it. that's all you have to on on that end,
the other side is you have log into your Taptalk account and set it up through your account on their website.
Now. ... If you are using rokbridge do NOT put in into your bridged folder, it won't work it MUST go into your root directory.
ex.
I use rokbridge. My bridged "path" folder is "forums" the main directory where my forums is in phpBB3. I put the mobiquio folder into my phpBB3 folder NOT the folder rokbridge is using as the "bridge"
