Flash Of Unstyled Content

[pvollmar]

I'm having a terrible time trying to fix my FOUC on a Foundation 6.7.4 site that I've used since V4 (which is why I'm still using float instead of grid or flex). You can see the site at https://test.stoutbowman.com/. I've tried everything I can find in the Foundation documents, forum and other internet resources, and nothing affects the resulting FOUC. In short, the off-canvas menu on the right appears and then slides to the right, and the page is scrolled down below the hero image and then returns to the top. I'll apologize in advance because despite the fact that I've been using Foundation for so long, I only ever work on this one site, and I'm not strictly a web developer but a financial advisor. Any help anyone can give me with this would be greatly appreciated!

I've accessed your site on several browsers and several devices and couldn't duplicate the behavior you mentioned. The off-canvas menu appears normally.

Thanks for testing this. The fact that it didn't occur on your systems led me to look at my systems. I was experiencing the porblem on my Ubuntu desktop (Chrome, Firefox and other browsers) as well as a Windows 10 laptop and my iPad. As an experiment, I turned off all my extensions, and the problem went away. I then turned them on one at a time, and found that it was my LastPass extension that was causing it, which is also installed on those systems. I looked at my LastPass settings and reset the "... read and change site data" from "on all sites" to "when you click on the extension" and the problem went away. Thanks again for your help.
