CSS messed up after upgrade from 7.7x to 7.8.2

I did all the steps to perform a successful upgrade, and all preflights check did without problems, however, after the final step was done, and the wizard finished, my css was messed up, in fact the problem now is there is a duplicate CREATE drop down menu and a duplicate administrator menu that’s messing the whole thing up!

Where are the files responsible to display the headers? So I can fix them?

  • Reapply the permissions again
  • do a quick repair and rebuild
  • try a different browser

… then tells us if it worked : - )

Is working with Firefox and broken in Chrome! really weird, on Mac OS X 10.10.5 Yosemite …

Have you tried clearing Chrome’s cache?
