When I tried to create new document library, Error says “save conflict. Your changes conflict with those made concurrently by another user. If you want your changes to be applied, click Back in your Web browser, refresh the page, and resubmit your changes.” When I go back, refresh the page and look in All Site Content, my library is there.
Can you help me with what is causing that issue?
I would expect that someone else may have created a library already with that name possibly. Has this happened more than once? I would expect it was a fluke.
