Hi all,
Thanks for all the responses on the topic. I havent had a chance to do any of the suggested steps yet but ill be sure to try them. I used the 1 click upgrade initially going from 1.4 to 1.6 without disabling my custom theme or modules and it lead to a rather broken store so i rolled it back and went with a new approach of building a store from scratch. Ill post again when ive gone through everything will my results.
