Hi, we would like to let you know that HMWP doesn’t physically change any WP files/folders. It only modifies .htaccess file (adds HMWP rules to it). So basically, deactivating HMWP should restore back the previous settings (if you have renamed wp-admin path then the line that you added in wp-config.php file also needs to be removed). In some cases you’ll need to manually remove rules from htaccess file.
Let us know if you still have any issue after your site is back.
