I cannot install your plugins. I manually tried add plugin with no luck, I have also tried uploaded via ftp with now luck.
I always get this error.
Downloading installation package from G:\PleskVhosts\aandeinstallations.co.uk\httpdocs/wp-content/themes/vw-painter-pro_1.0/vw-painter-pro/inc/plugins/vw-painter-pro-posttype…
Download failed. A valid URL was not provided.
As per your query, its look like you are getting the issue to upload the plugin.
If you want we can set up your plugin, make a user for us assign administrator role and send us the username and password along with the site URL at [email protected]
