Hey guys,

by now I had great success in creating my first sample page with SilverStripe.
My main aim is to integrate the Calender Module.
Therefore I got copied the module in my root directory and used the flush mechanism of the database.
After this, when creating a new Calender via using the Site Content Manager, I have got the following error message:

FATAL ERROR: i18n::include_by_class: Class EVENTCALENDAR not found
At line 1259 in C:\xampp\htdocs\sapphire\core\i18n.php

What solution is available?

Thanks for your answer.
I am running SilverStripe 2.2.3 on my localhost. Moreover I am using "modules-event_calendar-r22.tar".
I never used any other calendar modules.
I am not sure how to find out the PHP locale, but it might be de or DE for Germany. I had a look in my php.ini, but I was not able to find a related option.

Hope this information can help you.
Is there any advice for me?

I changed en_US to de, SilverStripe says:
FATAL ERROR: i18n::include_by_class: Locale file C:/xampp/htdocs/event_calendar/lang/en_US.php should exist
After this, I had a look into i18n.php, default_local is set to "en_US". So this could not be the reason for my error.
Hope for some helpful advice.

Regards from Germany
Marco

Originally, it does. But I renamed it to de.php, so in this case it does not exist.
But default_locale is set to en_US, so this error message is not anymore important.
I have copied the whole error message from the html code:
