Manual install for Plugin Extensions

Hello,

I’m having issues downloading extension for plugins due to proxy/firewall issues. I already tried to configure WP to use the proxy credentials and proxy bypass but it’s a no go. I decided to manually download the plugins and install them manually and that worked.

Some of the plugins have extensions which I’d like to install but since I cannot download them directly through wp-admin, I decided to download the zip files from the Github repository for each plugin but I don’t know how to install such plugin extensions.

I thought that by uploading the zip through new plugins in wp-admin I’d be able to install them but I get an error saying that no valid plugins are found in the file.

how can I install these extensions manually?

for example:
– ThemeFuse/Unyson-Shortcodes-Extension
– ThemeFuse/Unyson-MegaMenu-Extension
– ThemeFuse/Unyson-Backups-Extension

Thanks.
