Probaj iskljuciti adblock plus ako ga imas instaliranog u chromu, istu stvar skuzio i kod mene jucer, iskljucio adblock, sve ok.
EDIT C/P
It wasn't us, honest! An issue with the Malware Protection filter list caused YouTube to flake out today.
The folks who maintain the list quickly corrected the problem and released an update. To get it, just refresh your filter lists:
Click the AdBlock button and select Options.
On the FILTER LISTS tab, click update now.
Nakon ovoga radi ok, barem kod mene.
