Today I have updated the Metatag module to the latest version (7.x-1.0). However, I try to edit the metatags of a taxonomy term and, after saving the change, nothing changes (it doesn't save the changes).
I have been researching into the issue and I have read that this can happen when the metatag module is not up to date.
A new development version (7.x-1.x-dev) has been released today. I have tried downloading and using the development version (7.x-1.x-dev) and I still have the same problem. Is the problem related with database corruption? What do I need to do to solve the problem?
