Karen, as you usually complain about my longwindedness, I thought I would leave out as much detail as possible incase it was a not unexpected occurance to have major problems after an upgrade & there was a standard answer that usually worked like repeat the process; backup the store & then use the backup or something similar. Also I seem to remember reading weeks ago something on the forum about problems after upgrading; but I couldn't find anything doing a search.
I have received a private email suggesting that the problem is caused by me not having a phpsvexe file (whatever that is!) before I did the upgrade. Could that be the answer?
I forgot I don't have the site in my signature.
http://www.thegemlovers.com The emerald page is the one where the added information is not showing. It should look like the ruby page which I did after the upgrade & is ok. The sapphire page is the one that I had the problem with the H1 tag. You will find links to all pages from my home page - also all 3 pages are linked to the Gemstone page which is in my main menu.
