I’m trying to select an image for the JKreativ Medica Builder, but after selecting an image, it returns me an error (‘Uncaught Type Error:Cannot read property ‘url’ of undefined’);
It happens on jmetabox.js line 111 due to undefined thumbnail field in attachment.sizes.
I’m using the 1st July version of Jkreativ
How can I fix that?
hi grosmsm, thank you for your detailed problem. it seems your server unable to generate thumbnail. it may because of imagemagic or gd library not installed on your server. can you ask your server admin if both of those library installed?
After gd library installation it finally worked!
