Hello,
First of all, thank you for your purchase.
I checked filtering courses by category in the plugin on my test site, and for me, this feature seems to work correctly. Can you check, please, if you are using the latest plugin version: 1.0.2.2? If no, please update the plugin by registering your purchase code in the plugin’s ‘Main Settings’ and checking for updates for it from WordPress’s ‘Plugins’ menu. Please check if this solves this issue.
If you still encounter this issue after the update, or you already have the latest plugin version on your site, can you send me, please, temporary admin login credentials to your WordPress install, so I can check this issue out? Send it, please, to my email address: kisded@yahoo.com
Also, please provide exact steps on how can I see this issue in action (how to reproduce it on your site). Thank you.
Regards, Szabi – CodeRevolution.
