I have somewhat the same problem.
I don’t use the maintenance mode but I use this rename plugin.
Every time I visit the website and try to login, the plugin does not allow me to login. It redirects me to a 404 page and when I click on the home button to go to my front page, I need to log in again. The plugin blocks all login attempts.
The only thing I can do is the following: (maybe this helps for you to)
Login through FTP
Go to wp-content/plugins
Find the rename-wp-login folder
Rename the folder (i.e. rename-wp-loginnnn)
login to your website
After this the plugin does not work anymore, at least until you give the folder the right name again.
Thanks Lobster01. Yes, I deleted the rename-wp-login folder and then I could log-in in the normal way. Cheers
Perhaps someone has further thoughts on this Plug in Failing after one day?
I set it up with a good weird Login (www.domain.com.au/…….) – worked fine that day. I had multiple login/logout. Had the owner of the site also check access and it worked fine.
2 days later when I attempt to Login – Enter Username/Password – brings up error message “You must log in to access the admin area.”
Any tips appreciated. Thanks Dennis
Server error – duplication of my post above – so edited out.
