Thanks for your reply! I ended up taking away the kendo UI as I could reproduce the visual and functionality with Bootstrap, native in the worpress theme..
Sorry for my late reply but I have been busy in trying to reproduce the error. And I have been succesfull. I am using some elements from Kendo UI on the Website which is using the next jquery library: http://code.jquery.com/jquery-1.9.1.min.js.
This I put in the header of the site…
Disabling that library the cropping is working fine.. but the Kendo UI elements are not working anymore. I know of course that this has nothing to do with you guys.. but nevertheless would you be able to give a suggestion on how to solve that?
