Solution to error while uploading, error 403, admin-ajax.php

as the title suggest, im here to give a quick solution to this plugins users regarding error/stuck while uploading image through Wpdevart Gallery uploader.
the error code is 403 admin-ajax.php.

the solution:
1. login to your cpanel
2. find modSecurity under security category.
3. disable the modSecurity (remember to turn it back on when youre done uploading!!)
4. try uploading again & enjoy!

thanks to this SO answer, im able to figure out the problem: https://stackoverflow.com/questions/44667163/wordpress-website-shows-403-error-when-accessing-wp-admin-ajax-php-page-from-fro

for the dev:

anyway, your plugin rocks man, it fits my client need perfectly.
peace!
