Hi, you should have backed up HMWP settings by clicking on “export current settings” button. Anyways, please follow these steps:
– goto HMWP Start Tab, select “Medium Privacy – More Compatibility” scheme and save the settings
– goto Permalink & URLs tab and set “rename plugins” option to “all plugins”
Now you can proceed further from here and try renaming “wp-admin path” if required. Let us know if something specific is not working.
