Deleting a theme and upgrading
I purchased powerstore a few weeks ago but there is already an upgrade. On the instructions it says to backup the files and then upload the new files. Seems to me that the whole new set of files for the entire cart is in the upgrade, not just a few as I had expected. Is it going to get rid of all the work I've done so far? I know I need to backup the \themes but what about all the other work I've done, like uploading images, writing content, creating users etc.
My next questions is simple. How do I delete a theme from the control panel? There's only Select Theme and Edit Theme options.
