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?

Hello, I'm the developer of the EventCalendar module. I'd be happy to help you out if you can tell me which version of Silverstripe you're running, which version of EventCalendar you're running, and what your PHP locale is set to (e.g. en_US).

Have you installed any other calendar modules? if you at one time have had the "Calendar" module installed and then installed "EventCalendar" over it, you get some fatal conflicts.

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?

You can find out using "echo i18n::get_locale();"

You may have to create a set of translations in the lang folder. For instnace, if your local is "de", create de.php, and copy over the content from en_US.php. Then change all the "en_US" array keys to "de"...

Not really sure, though.. I'll keep looking. Strange error.

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

Does the file event_calendar/lang/en_US.php exist?

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:
