Tags not working

The tags are not working.

Explanation
For example when you create a new question, select a tag and click publish, when the page reloads you see that the tag is not selected in the question tags box. If you go to the tags admin page, you see the count in 0 meaning that no question has this tag assigned. Of course, the tag filter in the frontend is not working because this functionality is not working properly.
