I'm getting this:
The files associated with this add-on could not be found. Please upload them and try again.
I have Xenforo 1.5
You should if files were fully uploaded? Re-upload files.
Be sure that you have Xenforo 1.5 to use Xentag 3.x.I thought you were supposed to run either XenTags -or- XenForo Tags, but never both actively together.
