No events, "Cannot create property 'CPlastFetched' on string" on refresh

This has happened a couple of times over the last year: my calendar events (in the popup and new tab views) have disappeared, and clicking the refresh button shows an error:

Cannot create property 'CPlastFetched' on string '{"calendarLocale":"en","showDeclinedEvents":true,"hideWeekends":false,"weekStart":"0","timeZone":"America/Vancouver","format24HourTime":false,"dateFieldOrder":"MDY","defaultEventLength":"60","email":"me@gmail.com"}' 

I recall fixing it once by messing around with the view settings, changing the number of visible days/weeks and such. Haven't had any luck with that this time. Any ideas? TIA


  • JS console shows the error happening twice: popup.js:139 and extensionCommon.js:247.

  • Can you send me the background error logs:


  • Can do! Apologies for the delay.

  • Thanks for the logs, so we can temporarily resolve the issue by going into the extension Options .. Admin .. Reset settings to default.

    However, I would be curious if you can replicate the issue, what actions do you take with the extension that you might recall before the issue happens?
