Please do not use the vibe woocommerce widget ,there are issues in it as of now ,However for the Course review widget please follow these points :
1. Set a buddypress default avatar if you haven't any from wplms ->buddypress .
2. Add the gieven css from wp-admin -> appearamce ->customize ->custom css:
.course_review h4>span {
display: inline-block;
width: 100%;
}
1 - but that will overwrite the users avatars !
The corrupted avatars shown in the screenshot are the avatars of the removed users , So it's a false warring
Thank you
The X learner
That will only override the avatars of the users who did not have uploaded an avatar .
Yes you right , thank you
