FlexSlider Menu suddenly disappeared from CleanStart Theme, any idea how to add a slider?
First of all, please consult the documentation of the theme where you can find info on how to use the FlexSlider in the theme.
Then, if you can’t find a solution there, I strongly recommend you to contact the author for bugfix support. In this case to reach the author of Cleanstart theme please access this url: https://themeforest.net/item/cleanstart-clean-multipurpose-business-theme/8981419/support
Have an wonderful day!
