ical Patch - not working after Upgrade (?)

Hello,

We used the ical-Patch and had rearranged the ical-Url like described in the ical-Path readme file.
Everything was ok. In google-calender we could see the entries in the SuiteCRM calender (one way only).

But now (after the update to 7.1.5??) our ical links are broken again.

Even with Outlook 2013 we can’t connect to our SuiteCRM calenders any longer.

After entering the ical-Url the system is asking for an authentification (username+password)

We have tried every possible combination (account user name + account-password, ical key …etc.)
Everytime, the form to enter a name and a password pops up again.

Should we deinstall - or reinstall- the ical-Patch after the upgrade, or are there any other solution out there
to get the ical -connection in SuiteCRM running ??

Please help.

Kind regards
George

1.)
I found an icalender -Validator on this site:

The SugarCRM ical file is WRONG !!
We got the following message:

Your calendar is using an invalid newline format.

[size=6] Make sure to use \r\n to end lines rather than just \n (RFC 2445 §4.1).[/size]

Sorry, your calendar could not be parsed.

We have tested both: the Url and the ics-File from Suite CRM.

2.)
The described authentification problem with the ical-Url seems to be existing in Firefox and Chrome only.
In Opera we got no form to fill in the username and a password. :unsure:

Please help.

Same problem in Evolution calendar: asks for password and accepts none.

SuiteCRM 7.2.2
