PLEASE READ AND FOLLOW ALL OF THE INSTRUCTIONS IN THIS POST.
Note: refresh the website to test again after each step or it won't work.
1. Update uBO to the latest version (1.52.0+
) . <== The extension itself, for technical improvements. You do this in your browser.

2. Remove your custom config / reset to defaults. <== This means removing your custom filters (or disabling My filters) and disabling ALL additional lists you've enabled. It might be quicker to
make a backup of your config and restore to defaults instead.

3. Force an update of your Filter Lists. <== This is within the extension. Lists are what determine what's blocked or not.

How to update Filter lists: Click

uBO's icon > the
⚙ Dashboard button > the
Filter lists pane > the
Purge all caches button > the
Update now button.
4. Disable all other extensions AND your browser's built-in blockers. <== No need to uninstall, just disable them. They might interfere with our solutions.

Make sure you follow all 4 points above. If you're seeing the message, it's likely due to your custom config (either additional lists or separate filters in My filters).
Restarting your browser afterwards may help too.
Once you've gotten rid of the issue on default settings, you can slowly start restoring your config (if you
really need it). Do it gradually, to easier find out what was causing the issue in the first place. Once you find the culprit, simply skip it in your config.
If you want to use Enhancer for YouTube*, you have to*
disable its adblocking*.*
--- --- ---
DO NOT
- "Stack up" multiple blockers,
- Advise others to use multiple blockers at the same time,
- Advise others to add old filters
They will just increase the chance of anti-adblock. Any violation comment will be removed

I followed the 4 steps, but I'm still experiencing issues
The latest fix for anti-adblock was made on Oct 12, 2023 and currently corresponds to ID 606dbbab *.
* The ID mentioned above refers to YouTube's latest anti-adblock script. You can monitor it via this link:
https://pastefy.app/G1Txv5su/raw (top to bottom = oldest to newest). This means that the current fix is matched with the script with corresponding ID.
For example, in
https://www.youtube.com/s/desktop/c97476a7/jsbin/desktop_polymer_enable_wil_icons.vflset/desktop_polymer_enable_wil_icons.js, the c97476a7 part is the ID.
If
the latest ID (the last line)
does NOT match the current one written above, it means YT has updated it recently and you may encounter anti-adblock again.
PLEASE DO NOT REPORT IN THIS CASE.
If
the ID does match and you still get anti-adblock, kindly
repeat the 4 steps above. Thank you.
Uninstalling + reinstalling uBO, then force updating all your filter lists like in step #3 may also help.

The filter lists could be updated multiple times a day, so please always do step #3 before reporting.

If a new solution is pending, you should still be able to watch YouTube when logged out.
Please be patient, we're all volunteers that can't be online 24/7.
If the thread gets locked, it means
there's a newer one available. If the link doesn't work (mobile), please turn on desktop mode to reach it.

Last, but not least - please convince others
to do this since it's up to everyone's actions rather than an extension's.

uBO doesn't accept donations
We appreciate the sentiment many of you have expressed, but it is against uBO's
policy to
accept donations. What you can do instead, is to support other filter list makers by grabbing their website/donation info at the top of their filter lists (click the eye icon

next to a list to see its contents) and continuing from there.
