@vtrandev I think I didn’t describe my issue clearly. I am not having problems w/ access to my login page or Wp-admin login page. Instead, users are getting this access denied page when trying to access other pages on my website.
Just to be clear, this is definitely related to the SG security plugin, right? I thought that it must have been since it looks like the access denied page that SG security uses, but it might not be.
