I tried some time ago to upgrade from 7.11.7 to 7.11.8. Everything was OK in check part, but actual upgrade failed with a blank page, and reload gave me site without CSS or something elese went wrong (simple text links, etc).
I decided to put that upgrade on hold, and tried today to upgrade with 7.11.10 package. Same symptoms.
I see this in apache logs:
