[SOLVED] Joomla 5.0.0: ics format with errors

ah for me i had replaced the helper.php as it was mentioned and did download the most recent JEM 5.0.0 package.  
But you're right. it wasn't included in the package yet.  // Didn't check the whole commit 

The commit has 3 files, I think that you have copied one of them,

Sorry - did not see the other php files. 

Tested now on Joomla 6.1.2 with JEM 5.0.0 - replacing the helper and view files for events and eventlist.
 
For single events the download, for eventlist the download and subscribtion works fine! 

Thanks!
 

Thanks for reporting it, testing the commit and confirming that it's now resolved.

I tested some ics files and they were all smoothly imported into my calendar.
