Image upload not working

I tried everything i can but the image_advance is not working don’t know why it just suddenly stop.

I’ve done a fresh install of WordPress and the plugin.
removed all other plugins. and still no luck.

I look through the code one of the things stopping it was:

check_ajax_referer(“rwmb-attach-media{$field_id}”)

in the image-advanced.php

So i commented it add based on the code it should go straight to the foreach and start saving. but it still doesn’t

Please help me it very important
