Calendar has stopped working

[Jonsar]

@sdetweil Thank you, but I can only find 1 place in ical.js. There is one place in calendarutils.js but it is:
if(msTZName === ‘Customized Time Zone’){

The whole error I get is:

@Jonsar said in Calendar has stopped working:

yes, I said above that there were actually 2… in ical.js
and to make the second look like the 1st

yes, in calendarutils, 1, which I gave instructions to change

if(msTZName.startsWith(‘Customized Time Zone’){

@sdetweil Sorry, I missed the second one in ical.js. It works now! Thanks so much for your help.
