Just installed WP 5.6 and GP 3.0.2 fails to install. Returns with a no valid plugin found. After that I tried to upload the GP Premium and that installed fine (does’nt work I know, since it needs the GP base plugin).
I don’t get there, since it already gives an error while uploading the zip file at ‘New Plugin’.
And that’s where I went wrong…. I should upload it at Themes….
