Adblockers take a “dumb” approach…
I was just sat here wondering why an image stored in /content/banners/ would not display on my web page, but wiould show perfectly in /content/. Huh?
Till it dawned on me that the banners bit of the image URL was triggering the adblocker to hide it!
Ironically the image itself had the word banner in it’s name (and still displays ok with the folder renamed to logo).
I hate to think what would have happened had I not had an adblocker enabled.. try diagnosing that kind of bug report!
The moral? Always test your web pages with & without an adblocker.
