Hi
I have managed to sort out the marketing blocks. I have added my own HTML/CSS/JS for for the block. Which seems to be working ok.
Originally, I did use the code in the Readme file, the code for inserting the video caused the issue.
I am still having issues with blocks on the right hand side not being displayed when editing for front page is turned off. (RSS feed block, News feeds etc) cant seem to resolve the issue for this prob.
Thank you all for your help,
