A strange problem has cropped up on my site. But I do not know for sure if it´s related to sp?
I can not create a new user in wp backend anymore, I get the error code. “ERROR: The displayName You Have Chosen is not allowed on this site”
But registration work in general as it should. It is only in the wp backend that this phenomenon is found.
I have Googled for 2 days now with no results. Does anyone recognize this?
I’m running wp 3.4.1 and 5.1.2 and all plugins are updated to the latest version.
EDIT: Problem solved / I deleted all Blocked account names: Then it worked again. Strange.
