In the course of trying to edit a post that had its edit button active not greyed out I experienced something strange.
When I clicked on the edit button (which as stated above was not greyed out) this happened,
I was taken to a blank new page with the notice " There is a pending suggested edit in the queue. Try again in a few minutes"
- I would see the edit button greyed out if the above case were so.
- I won't be taken to a separate page on clicking on edit, it would simply present its message via a pop-up window as I try to access edit
Here is an image of the page I was directed to:
NOTE: was accessing the site from Kubuntu 16.04 guest OS in Ubuntu 16.04 host
