Ah ok, that makes sense. I had some users logging into the site that normally shouldn’t have been. (I have a modified plugin to map/create user accounts automatically from LDAP.) When those users logged in they didn’t know what the hell they were doing (a link was given to them inadvertently). It looks like when they click on a button that I’ve added to the admin dashboard top-bar (a posts button taking you to /edit.php) they get the following message:
You attempted to access the “(my site name)” dashboard, but you do not currently have privileges on this site. If you believe you should be able to access the “(my site name)” dashboard, please contact your network administrator.
And above that message is 4 copies of the error in question. So it looks like it happens when they click on a button that normally shouldn’t be there accessing a page that they don’t have access to ??
I can add a check to see if they have access on the code I put in to put the button there and make the button go away in that case, but I assume you may want to put some error checking on your end as well.
