I'm having the same issue and I have tried all the recommended solutions I've found online to fix this problem in the past. The same issue happens on multiple browsers so it is not a browser issue. I cleared all my cookies and that didn't help. I tried an incognito window and that doesn't help. I disabled all of my browser extensions, including my ad blocker and that didn't help. I can access every page on the website except for the activity feed. I see the menu and the page footer, but the body of the page is blank. 

Same issue here, mobile is fine, desktop Activity Feed is blank.  Looks like it's a problem on Strava's end.

Chris I tried all of the same avenues that you have tried. No success.

For me it's working again, that was 4 hours without dashboard in the browser.
