Greetings,
I am using OJS 3.1.2.1 on Windows 2016 server with XAMPP. When I try to add a plugin by going to Settings → Website → Installed Plugins and clicking on Upload a New Plugin, selecting a zip file and clicking Upload, I see a green check mark next to the zip file name. Then I click on Save and the "The tar command is not available. Please correctly configure it in your “config.inc.php”’ notification appears.
As suggested by @jnugent here, I downloaded Tar for Windows and added this to config.inc.php:
tar = “C:\Program Files (x86)\GnuWin32\bin\tar.exe”
with and without brackets, but I still see the same notification about Tar command not being available. What else should I try?
