@enthnys Yup, that's the workaround!

@arturga Downgrade to some previous version.

@enthnys Yup, that's the workaround!

@enthnys The "Messenger" site also doesn't work with AdBlock enabled, but the Messenger on Facebook site does work, probably due to Messenger on Facebook being different(coded differently? I'm not technically skilled here :/). The sidebar uses the "Messenger" site so it also doesn't work.

Edit: Messenger on facebook is like built into it, and probably falls under Facebook rules so it does work with AdBlocks because Facebook works with AdBlocks. While the sole Messenger doesn't work because it falls under different rules that doesn't work with AdBlock since today.

@enthnys They probably did but it's not like they will inform us, users. So it looks like the fault lies in Facebook itself.

AdBlock is at fault here, I use 2: the one that comes with Opera - Opera Ad Blocker and uBlock Origin, when they are both disabled Messenger works, but if either one of them is enabled messenger doesn't work.

So I disabled all my extensions and the messenger started working
I'll try them one by one now.

@enthnys Do you use any extensions? Maybe issue lies in them?

Edit: I just realised I haven't checked if messenger works without extensions.

It's not even the fault of the newest update, I'm on update from May and Messenger also doesn't work for me since today.

@leocg Yeah, it works on other websites. Both Facebook Messenger on sidebar and Messenger website doesn't work, it just shows full white site as shown in pictures above.
The same issue was reported on Opera subreddit, the issue is present on both Opera and Opera GX.
