how to clean file cache.

you should write to author of your cache plugin

it's not cache changing, you didn't clean file cache, so, site has new functions but styles for old theme

2. Currently, I can't help with widgets because I don't know what you did. You can make video with issue in next time

Logo issue is because you didn't clean cache after update.

Footer widgets is because you didn't update properly

Hi,

I just updated my theme, I notice that the logo size on mobile has decreased significantly, almost impossible to see. Before the update, everything was working fine. I don't recall making any chance to logo css or anything like that for mobile, and haven't changed the logo file for mobile either. Please assist.
