So recently I updated to OS El Capitan 10.11.2 and it has interfered with my Safari experience (I think). I am somehow not able to see any pages in my Google Drive (Docs, Slides, Sheets), but I can use every other site perfectly fine. I have tried force quitting, clearing history, but it hasn't fixed the problem.

I don't know if clearing the caches will fix it though.

When I open the error console in Safari it states the below about 14 times, then Safari reloads saying: "A problem occurred with this web page so it was reloaded." It will do this for forever until the tab is closed.

Invalid CSS property declaration at: *

At the moment the sites: Google Docs, Sheets, Slides, and Drawings don't work. And I am sure this problem is isolated to my machine since I can access those sites on other computers.

Also I have tried booting up in safe mode but I still can't access the sites.

Additional INFO:

OS X El Capitan 10.11.2

Safari Ver: 9.0.2

Macbook Pro (mid 2009)

  • Just to test if the invalid CSS property declaration is the actual cause of this, can you try opening this page which is an extremely simple page that writes 'It works' to the screen but also causes the same warning message?
