If your hosting provider supports PHP, we strongly recommend to use PHP version of Anti-Adblock code. Otherwise, you'll be forced to update the JS-code manually every time when new domains get banned by AdBlock.
Paste it to the source code of your website pages right after the <body> tag.
Do not use Standard & Anti-Adblock code on the same page! Anti-Adblock code works for all users.
