@amaye I think they might have fixed it. It was probably triggered by the web players on GX corner that i think got an update yersterday and bitdefender doesnt think of is a threat any more. Not 100% on that though you gotta give it a try and check for your self.
@thecollossaldan I have the same issue. Can you share what extensions have you removed? Cause I have thought this was cause of Adblocker, yet it was not.
For others with this problem, please goto the URL opera://about take a screenshot and post it. Or, at least mention if it says anything about an edition and whether it's std-1 or std-2 etc.
