I disabled all plugins except for Friends Only and another that needs to stay activated for the function of my site. The login prompt issue is now fixed – actually, it was before I disabled the plugins, so don’t know what was going on there.
However, I am still not receiving notification emails when users log onto my site. This was not an issue when I updated my blog in late March and was receiving notifications just fine.
The “Notify on successful login” and “Notify on failed login” options are both checked and my email is entered in correctly in Settings. Please let me know what can be done to fix this issue – thank you!
