  • Same issue here. Windows 8.1. It keeps reverting back to the leaf theme.

    It works fine on my Windows 10 machine, though.

  • renaming Opera didn't work for me
    so I uninstall opera then I delete opera folder in my system
    and re-install opera again

    problem solved..!!

  • I installed the Opera app two days ago.
    I tried to change the theme and the problem you have didn't happen to me. :lol:

  • Same issue on one of my laptops after an update to the latest version of Opera (both are Windows 10, but only one is having this problem).

  • I just fixed the issue on Windows 8.1.

    I uninstalled Opera, deleted the installation folder from my Program Files, and reinstalled. Opera recognized my account and synced all my extensions, bookmarks, and settings. Most important, the themes are finally sticking.


  • Actually, nevermind. It's going back to the same theme again.

    At least this time it's stuck with a better looking one. 😛

  • Have the same problem with Opera 32 using Windows XP Pro SP3.
    If I close and re-open Opera, whatever theme I saved will go away and the default Raindrops theme will appear.
    If I save one of 'My Themes', close Opera and shutdown the computer, the theme saved will return upon re-starting the computer and opening Opera. Of course, if I close Opera during the session and re-open...Raindrops again.

  • Problem continues with Opera 33.

  • They're never going to fix these issues. I don't know why I bother using Opera anymore.

  • Yeah... after all... themes are so vitally important to our everyday lives, right? LOL You're going to stop using Opera because the theme doesn't "stick", is that right? Seriously? I love Opera. I have no issues with themes on my Lenovo running Windows 10. Maybe it's time your checked your OS and installed programs before blaming Opera. Just sayin'.

  • The theme problem, always reverting to 'Raindrops, continues in 33. To test further, I installed the Developer and Beta versions of Opera. The problem does not exist with these two. A reasonable assumption is something in my settings, or something from continuously installing over the top, with Opera stable has been corrupted.
    However, I'll give stable(34) one more chance when available. If the problem does not clear I will start fresh with a complete and thorough uninstall. I'll post an update on the results.

  • Problem solved: For my system, uninstalling, including checking the box to 'Delete my Opera user data, and doing a fresh install solved the problem. The issue was a corruption of my Opera user data (see previous post). Bookmarks were saved to a html file. Cheers!
