Hi! I have the exact same issue as those above, website url to connect is https://website.com/l?o=g, when I login it redirect me to https://website.com/l (404)
The temporary fix I have is to rename the plugin (adding a letter), F5 (so I get connected), and rename the plugin back to have it working again..
Could you please put the fix public so I could use it as well ?
Are you using any plugin other than HMWP that modifies WP login path? It seems like there’s some conflict. Also, did you also rename wp-admin path name in HMWP settings?
Let us know your site’s wp-admin login details and FTP details (as private reply) so that we can look into the issue and fix it at the earliest for you.
