I did not have a solution yet.
Just FYI: I met a problem with local setup of your site copy. It’s the 1st time when even after removing from a copy all mu- and casual plugins, activating WP default theme and comparing all WP files with wordpress.org’s WP 5.0.3 installation package I still can not login to the local site copy – it reports about troubles with cookies. The 10+ other sites allows to login from the same browser but this copy does not… So I still finding what may be wrong.
Btw., can you try to deactivate temporary “iThemes Security (Better WP Security)” plugin? I have assumption that it may be a reason of a conflict with URE Pro admin menu access add-on. Let me know the result.
