Bob,
Thanks for your work and for your kindness in sharing it. It’s not always easy for someone to invest a lot of sweat and then share it for the public good. I know you’ve mentioned fixes to help people with login issues. In my own case, here’s exactly what I experienced. Perhaps it may help others.
1. I didn’t have “Theme My Login” installed. But I was using a custom profile plugin I bought called UPME which enables me to redirect mysite.com/wp-login.php to redirect to mysite.com/login
AND
redirected mysite.com/wp-admin to https://mysite.com/login/?redirect_to=https://mysite.com/wp-admin/
2. I was unable to login after installing the easy pie.
3. I renamed the plugin folder to have an underscore prefix, then refreshed the wp-content folder as well as the public_html folder but I was still unable to login using mysite.com/login and mysite.com/wp-login even after clearing browsing history and browser cache. The coming soon page continued to show with plugin folder renamed..
4. I deleted the plugin folder entirely, but was still unable to login after clearing browsing history and browser cache. The coming soon page continued to show, even with plugin folder deleted.
6. I now figured that the cached WordPress state was still serving up the page. If only I could log in and clean the wordpress cache.
5. Luckily, I was eventually able to login by typing mysite.com/wp-admin which redirected to https://mysite.com/login/?redirect_to=https://mysite.com/wp-admin/
6. Once logged in, I used WP-SuperCache to clear existing WordPress cache. Only after did the coming soon page go and everything return back to normal.
I have taken the steps to share my experience testing this so it can help others and also give you and insight into how to advice people as well as continue to improve the plugin. Thanks again for sharing.
