Hello @gnapse, I am able to reproduce this issue on Windows 10, non-retina display. Both Chrome and Firefox.  

@CentroDL, the from column name on refinery_calendar_events table seems to be what is causing this issue since [it is a sqlite keyword](http://www.sqlite.org/lang_keywords.html). I've replace from by start [here](https://github.com/jvalente/refinerycms-calendar/commit/5498c976ed2b77734a9a58dfe67de8116d244c35) and everything...
