Hi @socraticus,
Thanks for contacting us about being unable to access the Style Panel, as this definitely sounds like odd behavior.
I tried reproducing this behavior on my end but was unable to as you may see in the following short screen capture: Screen Recording 2019-03-19...
Can you please try the following:
(1) Try to reproduce the error while being logged into Webflow using Incognito mode with browser extensions turned off: Browse in private - Computer - Google Chrome Help
(2) If the problem persists, please take a screenshot of your Console and send it to me: Image 2018-04-10 at 12.28.2...
Thanks in advance! We’ll be here to help
