Uninstall - removes all your forum data/tables.

You can download other versions here:

Hi,

After uninstall wpforo then delete plugin and clean dtb via wp-optimize i still have tables in database i delete it via phpadmin like 

Trying install wpforo-beta 1 and 2 and test in this version and after update to beta-5. Same result (Add Error).

I ask on forum provider what's wrong.

The Uninstall function have not worked. And as far as I see nothing works there from wpForo. I'd recommend delete this website, and start from scratch. Or you can clone it and remove all plugins, install the default theme. But I don't hope it'll work... Something is basic wrong or inserted in db wrongly so you need fresh website.
