RuBeQK. I can appreciate and applaud your apprehension. Too many people just move ahead without a clear understanding of what they are doing and mess stuff up. Here is what I hope are more clarifications.
- Before doing anything go to ATO>Import/Export Settings and click on the Export & Download Atahualpa Setting File - Now you have a backup of your current setting.
- The settings you just downloaded are all the settings in the Atahualpa Theme Options. Style settings, path settings, etc. In other words anything you "set" in the options. If you upload the round style it will overwrite ALL those settings.
- If you import the round settings and don't like it you can just go to ATO>Import/Export Settings and hit the Upload & Import Atahualpa Settings File button, select the file you exported previously and you will be back to where you were.
