Hi Roven,
I got my Read More tabs back by following the instructions on the following post.
https://colorlibsupport.com/t/more-link-not-visible/.
For others.
Go to: Appearance > Customize > Sparkling Options > Content Options > Check the Show Post Excerpts.
if the Show Post Excerpts is already checked, unchecked it and then check again. It should work for you as it has done for me.
By the way Rovin, thanks for your support.
Best Regards
Khurram
