Parsing error

[PBH148]

Hi folks, I am completely new to this environment so please forgive me should I commit any faux pas! I am not a coder, but I know more than most about IT.
davx5-debug.zip

Having just installed and configured the DAVx5 app on my Android tablet to access my calendar which I recently ported from Google to mymailhosting.com, I now get a parsing error when it syncs. Looking what has downloaded, it appears compete but I would still like to fix the error. Is this the right place to ask?
Debugging info attached.

Hi,

you're using an unauthorized copy of DAVx5. Please install the correct one: https://play.google.com/store/apps/details?id=at.bitfire.davdroid Thanks!

For the error - if it still pops up when using the real DAVx5 please open this in a web browser:

https://mx4125.usc1.mymailhosting.com/webdav/calendars/hama.org.uk/peter/6236848ab9b1417694083530fc2861f4/ig33ci1no4lh5oejnn6ngh02cl@google.com.ics

download the ics file and send it to us via our ticket system: davx5.com/support - then we can take a look at the error in detail and hopefully reproduce it.

Thank you!
