Just one more quick note on the Magento upgrade to 184.108.40.206. The new full text search functionality uses an index that does not get built when you upgrade. You will need to manually rebuild it in the UI to get your store search working.
To do the rebuild you access the Cache Management page (System > Cache Management). You will see a new button at the bottom labeled ‘Rebuild’ – press it and depending on how many products you have the index will rebuild in a few seconds or minutes.
Once rebuilt it works well, enjoy!
