Before posting, some required (mandatory) steps

First of all you should check if the problem is not being caused by an extension or a broken profile. Do the following required steps, re-starting Opera after each one of them and checking if the problem remains after each one.

• Disable all extensions

• Disable the ad-blocker/tracker blocker

• Reset settings to default (Do a backup and export your passwords first)

• Reset flags to default

• Create a clean profile folder/directory

• Temporarily disable antivirus, firewall, anti-malware and all related software in your system

• If the problem is with a web page, check if it works with other browsers. Try checking with other Chromium based browsers

• Check if your Windows is up to date

Posting about your problem

@Keerat06 Just replace the content of the new profile directory with that from the old one.

@vader1950 There is nothing you can do beside wait for the adblocker to be updated and able block YouTube ads again.

You can try installing an adblocker extension and use it until the same issue start to happen.

@vader1950 Opera One, Opera GX or Opera Air?

@Keerat06 Yes, you copy the files and paste them somewhere else.

@MickBeaman Did you try reinstalling Opera?

@daniloperetti Go to settings > Privacy and Security > Site Settings > Notifications and remove the site that is sending the notification

@teligence Opera One, Opera GX or Opera Air?

@DanneyB Go to auth.opera.com and use the Forgot Password? tool.

@Keerat06 You can find the path to the profile directory in opera://about

@danielbaharier Did you try changing to your Gmail account?
