Strangely enough, I got the same exact problem (error 500) with another server, but now with spreadsheet format, while iCalendar works!

@IRA1777 Could you try SRF 3.2.0. The previously failing export on ICalendar format works now (I am no Fx). The difference for that wiki was the upgrade of SRF.

SRF 3.2.0 works fine, spreadsheet and iCalandar. Thx!

Cool. Thanks for reporting back!
