Ok first do a complete backup of the site.
Then go to
ACP--> Settings --> Options --> BB Code Settings --> Enabled Built-in BB Codes set the
Allow Link BBCode to no.
Then go to
ACP --> Maintenance --> General Update Tools and run the
Rebuild Post Cache
Now any links such as
https://vborg.vbsupport.ru/showthread.php?t=254263 should show up like this, [url]https://vborg.vbsupport.ru/showthread.php?t=254263[/url]
Hopefully that will satisfy adsense, as you no longer have live links to sites.
