just bought the plugin
and i dont have the zip file to uploud to my wordpress admin panel
I think you bought a jQuery version. If you want to use in WordPress you have to use a Wordpress version of the plugin.
If you purchased a Wordpress version one you can follow this docs for more installation details: https://docs.sonhlab.com/wp-openpanel-more-space-for-wordpress-sites/
Or you can provide me your purchase code at here: https://talk.sonhlab.com/licenses
Then, I will check it for you.
