There was an edge case compatibility issue between Buttons Factory Pro and the latest version of Concrete5. After receiving notice from a client that a certain element wasn't working, and doing my own troubleshooting, I came to the conclusion it must be related to a recent core update. I contacted the developer of this add on about it and he confirmed the issue and said he'd work on it right away. Within a couple of hours (or less), an update was pushed that resolved the issue. Very impressive!

This is the best button add on for C5 out there by far. Simple and easy to use and has great support behind it. If your considering this for your site I encourage you to get it and make your button life simple.
