This is likely happening due to one of these reasons:
One of your enabled filters contains a 'bad' filtering rule. Click on the extension icon and then on the gear icon in the top right corner. Go to the Filters tab and disable all filters to see if that will fix the problem. If it does, start re-enabling them one by one, checking after each filter if the website(s) are displayed as they should. This will help pinpoint the problematic filter.
If it's one of AdGuard filters, let us know about it by contacting firstname.lastname@example.org
, and we will fix the problem.
You have created a custom filtering rule that messes with the website. Click on the extension icon and then on the gear icon in the top right corner. Open the User rules tab and comment out all active rules by adding a
! symbol in front of each of them. If it fixes the problem then of the custom rules is causing the issue. Start removing
! from these rules one by one until you find the problematic rule.
