I am reporting this as a possible bug. I find that when I click
Create Tag Wiki to create an entry for a tag on PMSE Meta, the page reloads back to the same page:
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 the button below to get started.
(Note that if you have less than 4000 reputation, your tag wiki will be peer reviewed before it is published.)
Note that this works fine on the main PMSE site.
