I keep getting an error message in Chrome extensions. This is the message I get:

avast! Online Security
This extension failed to redirect a network request to data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAFElEQVR4XgXAAQ0AAABAMP1L30IDCPwC/o5WcS4AAAAASUVORK5CYII=
because another extension (AdBlock) redirected it to data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAACklEQVR4nGMAAQAABQABDQottAAAAABJRU5ErkJggg==.

How do I direct AdBlcok to allow Avast to run properly? I'm not getting rid of Avast so i have to fix AdBlcok.

    Hi and sorry for the late reply! Your best bet is to report this to Avast and ask them to "change the data: image used for PNG replacement to match AdBlock's," and include the error message you showed us.

    AdBlock and other extensions have agreed to use that specific PNG data: image to stop this error from happening, so Avast can do the same to get the error to go away.

    Hope this helps!
