@elking82 A moderator (me) can edit your original post to add a "Solved" tag and then lock the thread (though if it comes up again you can message me and I'll unlock it for you).

@leocg Thanks, man! It was the blocker, indeed!

@leocg can you close this topic- issue is resolved

@leocg Yes, in general I agree. Patience is good. And I tried to wait this out a bit longer. But this seemed to be a problem with the data to be submitted itself - which got wrongly or malformed picked up, I would assume. And hence raised an error on the server side. In the end. Not with the server in general.

@val0194 Good to hear that it's fixed.

@burnout426 Forgive me, please. I am so sorry. You are right. There is such option in latest version. @leocg Please, close this thread.

Thank you for the reply. Sorry, forgot to mention – OS Win 10 x64. I did everything mentioned in 'Before posting' before creating this topic, except checking with other browsers – problem was with every webpage I opened. A few hours ago I launched memtest86 (had three BSODs in a row), and seems I have troubles with one of my RAM sticks (2x8Gb Vengeance, which I bought on 7th of Dec). Since it is very likely to be a hardware problem, I believe we can close the topic. Sorry for bothering and blaming Opera

Oh thanks, sorry for late reply.

I guess it's working properly now. All I had to do was disable Opera Turbo and now it functions very well, except for one website which doesn't work on any browser on my pc but works on my other devices. I think this isn't the right place to post about it so thanks anyway guys

zalex108 Thaks for advice. Needed to add Opera to exclusion list on AV.

@zalex108 Thank you for reply! I could download DMG file from this FTP page. And I could update to 49.0.2725.56. Thank you! https://ftp.opera.com/pub/opera/desktop/49.0.2725.56/mac/

@burnout426 it works. Thank you!

@leocg Thanks a bunch. So simple, it was staring me in the face all along and I just didn't know where to look for it One more step up the learning curve. Hopefully I'll know enough about this to help future newbies. Bob

guys panic over i deleted all cookies for paypal logged in and hey presto... now saved

Hello, the goal is not to use an extension but the native advertising blocker Opera. I found, just turn off all lists, thanks

Hi. Sorry about that. The problem comes from the fact that we had to change cookie domain for security reasons - which means that for some users you need to delete old cookie otherwise it will keep interfering (your browser will keep sending it along with the new one). Clearing cookies (all or just for opera.com domain) is the correct solution for now. But I will deploy a fix today that should solve this permanently for all - the downside being that it will log everyone out of the Forums. Sorry again for all the inconvenience caused! [UPDATE] Permanent fix deployed. Please let me know if you still experience any problems! (The fix causes everyone to be logged out of the forums - that's expected and cannot be worked around).

@sgunhouse hey thanks! It didn't work when I turned off opera built-in adblocker but it did when I turned off adblock plus. Button shows now and all ads still blocked on the site. Thanks much for your help

Wow! Thanx man, that was Reader View extension. After removing it the site worked again!

Thanks for the info.

I had this problem because of use Open DNS.
