Problems with blogging and error message in the frontend

Hello Developers,

I discovered your CMS and would like to work with. I have installed it already under http://textpress.wpzweinull.ch and have the frontend this error message.

Warning: array_key_exists() expects parameter 2 to be array, null given in /www/htdocs/xxxxxxx/textpress.wpzweinull.ch/src/shameerc/Textpress/Textpress.php on line 213

Warning: array_key_exists() expects parameter 2 to be array, null given in /www/htdocs/xxxxxxxx/textpress.wpzweinull.ch/src/shameerc/Textpress/Textpress.php on line 564

And I still do not know how an Article has to look at the letter. What are the meta tags. The information that I have from your guidance, do not work.

Look it up to you, please check my blog linked above in the news. I uploaded a .txt file and no Articles header and no Teaser displayed.

How can it be, and how can fix the error in the frontend?

Thanks in advance.

I had this error too when I created an article under Windows and then upload it to Linux server. Then I created another article under Linux and it worked well. The problem should be related to end of line.
