I edited 2 or 3 tags clicking the 'Tags' menu at top and then:
Either clicking the "help us edit this wiki" or, when hovering over a tag, clicking the 'edit' mark.

What is the cause of this error?
There are a lot of tags, where if I try to edit them, this message is displayed. Could it be because it hasn't been used enough or something like that?
