I am trying to update my plug in; I just purchased the Post Grid Starter for 19.99 so I can filter post according to category. It is not working; I am not able to upload the plug in. I also tried to update the License Key, thinking it was out of date, but I am not able to enter that either.
I have been using your post grid for over a year, without any issues...
Welcome to our forum.
Please download from here first https://www.pickplugins.com/my-account/downloads/
and then delete the existing (older version) plugin and then reinstall the plugin (new version).
Please see the screenshot where to put license key.
Let me know if you have already license key https://www.pickplugins.com/license-list/, otherwise, i will generate for you.
