Symfony website crash

After upgrading Shield today to the latest version, 2 plugins that were playing just fine together apparently no longer play nice together. I’m getting fatal errors from both Shield v18.2.11 and HurryTimer v2.8.1. I’ve reported this also to the developer of HurryTimer, but these 2 plugins were fine together until today. The errors I’m seeing crashing the website:

I’ve had to disable HurryTimer as it is erring out more often now, but the client wants a timer on their website for next year’s eclipse. It would be nice if these plugins could get along again?
