I had a lot of trouble altering the shop front until I realised I had deleted the text editor for the front page, so that confused me even more I had to reload the text editor module which took half a night trying to figure it out , but got there in the end,.
This system of modules and hooks makes life so frustrating trying things out for the first time as a new user. I would have thought a simpler system could be employed to amend your front page instead of relying on umpteen modules to get it looking as you want it.
Cannot resize any blocks with this facility in Chrome 17 so its "Not cool" with me!
