I only fiddle around with Opera a bit to check compatibility on different sites I’ve developed, so I’ll admit I’m not an Opera guru, but I did manage to fix a bizarre issue that caused some frequented sites to show up with an error saying it was blocked, even though I was sure I had not blocked it.
To undo the block, right-click on the page, select "Block Content", and click the "Details" button to edit the list of blocked content.
So of course the first thing I do is try what it suggested, but the sites were not listed as being blocked. So I tried adding them, restarting Opera, then removing them. Nope, that didn’t do it either. I found a few threads discussing the same issue and they suggested editing or wiping out a certain config file to reset it. I didn’t really feel like doing that so I clicked around some more and stumbled upon the solution.
- Right Click (on affected site)
- Edit Site Preferences…
- Content Tab
- Uncheck “Enable content blocking”
- Click OK
So it was a fairly obvious solution, but not at all what the error screen was telling me what to do. Good one Opera.
