One of our designers made an error today, placing images they wanted to appear in a directory called “POPUP”. We use the JavaScript library Lightbox to give smooth popup images for products in the website, so popup in that sense was appropriate.
The anti-virus solution we have has advertising blocking in it. This software running on the client machines blocked the functionality of the page. Thus making it useless.
After consulting me as to what the problem was, a lesson was learnt.
Don’t use directories names that sound like spam on your websites!
