Certain websites require you to allow Ads in order to access the content on their site or the site may just also be incompatible with the extension.
In this case, you can "whitelist" the website to allow ads on that particular site without turning off your Adblocker entirely.
Heres how:
1. Open Google Chrome
2. In the upper right-hand corner, click on the Adblock Pro icon:
3. Next, click on the "settings" icon:
4. Once in the settings menu, click on Whitelisted websites in the left-hand menu and then enter the site domain you'd like to allow ads, then click Add Website
*It is important to note that you will have the most success whitelisting a site if you enter the most basic web address for the site. (i.e. enter yahoo.com rather than https://www.yahoo.com/entertainment/jake-gyllenhaal-mysterio-spider-man-213012746.html to allow ads on all yahoo pages)
