Hello.
I use the plugin on my wordpress blog (hamradio.gr) but although i have set " define('WPLANG', 'el'); " on my wp-config.php file i got ???? i get ???? instead of months text on the widgets. all the other texts as event details is shown correctly.

What can be wrong?

Dear Antonis,

This was a bug caused by a translation problem within Spider Calendar. It was resolved with an update, which is already available on WordPress.org.

Please install the newest version and the problem will be fixed. If you have Spider Calendar Lite, simply go to Plugins page of your WordPress admin panel, find Spider Calendar and click Update.

In case of pro, please deactivate and delete current version and then install latest.
Thank you!
