Is there a way to have an adblocker detected and a message asking them to whitelist our site?

What you're looking for is called a paywall or ad-blocker detection script.

For Invision Community (IPS) forums, you'll want an IPS-specific plugin from the Invision Community Marketplace (or third-party vendors like Invisionize) or a custom JavaScript snippet that detects missing ads by checking elements/script execution, which you'd integrate into your forum's themes/hooks, often using solutions from the IAB Tech Lab, AdSanity, or Advanced Ads for inspiration, as these solutions work by looking for blocked ad requests or zero-height ad containers

I'll bet one of the third party guys has something already but they take a lot of updating because adblock browser plugins continually change to thwart ad-blocker detection scripts.

[IPS Marketplace] Enhanced AdBlock Blocker

With this plugin you will be able to detect AdBlock browser plugin that blocks your website ads. It will display a block message that will disable all website if the user didn't disable his AdBlocker.

The above as a starting point but you'll obviously want something updated and current. You'll just have to start contacting people and looking around. I know SOSinvision has a lot of stuff and so do a lot of the other third party guys which I hope will chime in since I don't know them all. Good luck.

Appreciate it.

Does anyone else have any current solutions that they use that are easy to update into a theme?

There is no application currently that auto detects it, but you could use the page editor and put up a simple block asking members if they use it, to disable it to support your forum.

I’d be happy to look into a custom development application if you send me some details what you’d need specifically.

Thanks. I'll probably just add a notice at the top.
