Hi Kathryn,
thanks for your quickly reply!
some more questions before try this:
1. should I uninstall the actual theme or just overwrite the sketch folder under themes folder by moving the new unziped folder?
2. should I export an xml to keep the settings, pages & things like that before I do it and import after the fresh install or this process keep things like they are now? (I believe the answer is no, but is better ask than make mistakes…)
3. the little tweaks I made on CSS were made via Custom CSS, so I don’t need to worry about it, right?
once again, thank you!
