I've created a number of tag wiki pages on SO before (my rep is 3.8k), and they were accepted. Since a few days when I try to create a new tag wiki I get a page with text:
There is no tag wiki for this tag … yet!
Tag wikis help introduce newcomers to the tag. They contain an overview of the topic defined by the tag, along with guidelines on its usage.
All registered users may propose new tag wikis. Click Create Tag Wiki below to get started.
(Note that if you have less than 20000 reputation, your tag wiki will be peer reviewed before it is published.)
but there is no Create Tag Wiki link below...
Is it a bug or I do not have permissions to create tag wikis? In the latter case a relevant message would be welcomed.
PS. I can create tag wikis on other site without any problems.
