The form validation script didn’t load

If your internet is slow or a content blocker (ad-block, tracker blocker, VPN, antivirus web shield) is running, Opera’s sign-in JavaScript might not have loaded, so the "Next" button stays inactive.

Fix: Disable any extensions temporarily, refresh the page, and try again.

Corrupted browser cache

If the Opera sign-in page is cached incorrectly, the button can break.

Fix: Clear cache + cookies for opera.com, restart Opera, and try again.

Outdated Opera version

Older builds sometimes have UI bugs with the account login modal.

Fix: Update Opera to the latest version.

Wrong field focus or invisible whitespace

If the password box has trailing spaces or the cursor never actually registered a typed password, the “Next” button won’t activate.

Fix: Retype the password carefully, no spaces, and ensure Caps Lock is correct.

Server-side sync issue

Sometimes Opera’s sync servers have temporary downtime, and the login form just won’t submit.

Fix: Try again after a while or check Opera’s status page.

If you want, I can also tell you a quick way to bypass the in-browser login and sign into your Opera account directly via the Opera web account page, which often works even when the in-app form is stuck.

Do you want me to give you that direct login method?
