follow all these indications:

• clear cookies / localStorage/ cache for the tested page
• reset uBO, don't modify any uBO setting, update all the filter lists, don't add any other list (other than your regional list)
• disable any custom filter for that site
• disable any other extension / addon in your browser, disable builtin blockers /shields/ tracking protection in brave/ opera/ vivaldi/ edge/ firefox etc
• if Opera browser: open opera://extensions/ and check the "allow access to search page results" option
• disable (if any) the web shields in your antivirus / antimalware software / other blocking software
• are you using a DNS which features adblocking (like AdGuard DNS)?=> test using another DNS (google for example => IP addresses 8.8.8.8 & 8.8.4.4)
• restart the system, reopen the browser, test again.
