Latest 1.2.2 Fixed my issue with uploading.

Hi, @bilimokur your theme is including an old version of jQuery v1.11.2, it overwrites the default jQuery version (v1.12.4) bundled with WordPress which causes a problem.

The best way to fix that would be to stop the theme from loading the old jQuery version. I am not sure where this code but i am guessing it will be somewhere in the theme functions.php file. If not then you can ask your theme support about it.

Specifically, the file which causes a problem is /wp-content/themes/mimarihaber/js/jquery.min.js

Ok. I will update my jquery version. Thank you.
