since some days my Simple tags plugins works strangely.
When I add a tag to an existing article, a new category with the same name of the tag is created! (but only if the tag doesn't match an already existing category).
This is really annoying, because this new category appears as a new item in the main drop-down menu of my website.
So every time I add a tag to an article, I have to remove this newly created category.
Even more strange, it doesn't happen in the local copy of the same website (on my PC)!
What can I do to fix this behavior?
