Hi, please follow these steps:
– goto HMWP Start Tab >> select ‘Medium Privacy – More Compatibility’ scheme >> click ‘Save Settings’
– goto HMWP permalinks & URLs tab >> set “rename plugins” to all plugins
– goto HMWP Start Tab >> click ‘Multi-site Configuration’
– now use a FTP program or your host file manager and add those lines to your htaccess file (after RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ [-])
If it’s still the issue then please let us know your site’s wp-admin login details so that we can look into it further.
