I got mine to work by selecting all in the Opera stable appdata roaming file and deselecting the default. and copying all into the default. All were restored including my addons. No cookies were saved. This was a complete restore to almost normal

@ftfire Thank you, it worked

@derekhopkins said in cannot import any bookmarks:

I cannot import any bookmarks from HTML File or from Edge .It comes up with message saying done but none appear

This is not my fix but it does work.
This work for me. Go to your profile folder (My is for example here C:\Users\Ohaha\AppData\Roaming\Opera Software\Opera Stable)

Delete files:
History
History Provider Cache
History-journal
Restart Opera.

@ftfire Thank you, it worked
