Reply To: IE

Hello,

In order to solve the issue with the white gap add this code to the Theme Settings > Custom CSS > Global:

.vc_ie-flexbox-fixer {
   display: none!important;
}

As for the other two issues, you have JS error in the console which is caused by one of your plugins. Deactivate all the plugins not related to the theme, check the issue, then activate the plugins one by one to detect which one causes the problem.

Best Regards
