Oops sorry... I'm was starting to lose my mind and didn't read your post properly!
Thanks so much! It was set to 1, however there was something in my shopping cart so it should have been showing but somehow what was in the cart has now disappeared.... silly mistake... lesson learned... when things don't make sense get some sleep!!! Will sort out the disappearing products from the shopping cart another day!
Thanks soooo much!
And thanks gjh42 for the heads up on the single column setting
