wolfman123 on "[Plugin: Contact Form 7] Warning: Illegal offset"

Hi,

I do have this problem since updating the plugin:
Warning: Illegal offset type in D:\hosting\6799661\html\wp\wp-content\plugins\contact-form-7\includes\shortcodes.php on line 15

if you google for:
"Warning: Illegal offset type in plugins\contact-form-7\includes\shortcodes.php on line 15"

you'll find thousands of those entries..

Can you tell me how to fix the problem?

Thanks
