Addition of calendar plugin leads to webmail failure

Hello,

I am using RC 1.4.4 with elastic skin (which is great, thanks!) on CentOS 7 with PHP v7.3.13 (and Apache).

I added the calendar plugin v3.5.2 following the directions I found here: https://packagist.org/packages/kolab/calendar#3.5.2

The application appeared to work fine initially, but users started complaining that in the main web mail interface they could not open their messages: When clicking a message title to open it, it would not open; the blank window remained blank.

I found the following error in the php error log (repeating continuously, obviously every time a user attempted to open a message:

Any suggestions to correct this issue will be welcome! Thank you!

If I should file a bug, please let me know!

I have temporarily disabled the plugin (which stops the error from occurring).

Cheers,
Nick
