Sorry for the delay responding to this.
Have you tried this again recently? From the screenshot, it looks like perhaps it's not letting you due to your Mediawiki integration having been recently enabled. i.e. there is a waiting period before users are flagged as "Autoconfirmed" and allowed to edit pages.
I thought this had been fixed a while back, but perhaps it has resurfaced.
If you can edit the wiki now, then that was the issue, and it needs to be fixed. If you still can't edit the wiki, then there is another bug that needs to be fixed. Either way, let me know.
