If the past few days you’ve been seeing text where chicklets should have been you’re not alone. Somehow, a folder on the server got renamed and caused the images to be not found.
Granted, I have fixed the issue, but if you were seeing text were there were once chicklets, than that means your not hosting your own button images.
Download the button images, and upload them to your server. Then update the paths so you are referencing the images on your server. This will prevent any future issues and it’ll be cheaper for me.
