Thanks manhta for your rapid-fire response.
That partially worked...
For some reason though, it only worked for one Course Category.
For instance, we have a course category named:
https://kissielts.com/courses/4-1-on-1
And every course listed here, has a sidebar with a clickable link called, "Take This Course"; which take them to a cart page: for example:
https://kissielts.com/index.php?option=com_guru&controller=guruPrograms&task=buy_action&course_id=68
It is the same sidebar from the one we changed before, so i am lost as why this one didn't change like the other did. Perhaps, its because its a different course category?
I reviewed the tabs.php, but was lost and didn't want to make a mistake...
Any chance you know what I am talking about and have a fix?
