After updating the Bootstrap from the original version 7.x-3.0 to the last version 7.x-3.6, the following error message appears on page ..../admin/appearance/settings/online:
jQuery Update is not enabled, Bootstrap requires a minimum jQuery version of 1.9 or higher. Please enable the jQuery Update module....
Any further change of jQuery version to 1.9 or higher, leads to different theme errors, like
- MD Slider may stop working or not displayed at all;
- image selection on product page may not work;
- other image related errors.
I am VERY DISAPPOINTED with the support team - NEVER COME BACK to buy any other theme !!!
