Thanks man. It works incognito, good advice. Glad to know it's working for others. Chrome is up to date, but I'll check for any settings that might be the culprit.
Is anyone else getting an incorrectly-formatted home page like this? Occurs after clicking to enter my site (https://www.redguitar.com) from the video intro. Has been working fine for years. Screen grab is from desktop Chrome. Appears to be working fine on Android mobile. TIA for any help!
