If you were trying to install ShortPoint Add-In, and you noticed that install button ( or upgrade button ) seems to be broken ( see the next image ), then this article might help you get this issue resolved.
ShortPoint is trying to access a file from a site that has been blocked by the AdBlock Chrome extension,
