Error: 0 is an invalid number

Hello,
Thank you for using our plugin.
Can you please give more information about your error ?
Have you chosen at least one category and one author ? if yes, have you associated an image to your course ?

Best regards,

Hello,

I am actually having the same issue. I was able to actually create one course and for whatever reason I can’t create anymore. I named it, wrote a description, added an image, assigned it a category, & assigned it an author. I also used variations of authors and categories and images etc.. to see if that would change anything. I am using the Membership Pro 2 Plugin and am not sure if that is causing the conflict or not but seeing as how I was able to add one course but no others I don’t see how that could be the issue. If you could please help me figure this out it would be greatly appreciated.

Thanks,

Kate
