Hello,
I am a newbie in Typolight et its my first site with this great cms.

But I have some problems in establishing forms.
When I populate a form (standard or automatic), he folowwing message appears :
Warning: strlen() expects parameter 1 to be string, array given in I:\xampp\htdocs\psisecurite\system\drivers\DC_Tabl e.php on line 2793
Warning: Cannot modify header information - headers already sent by (output started at I:\xampp\htdocs\psisecurite\system\functions.php:1 22) in I:\xampp\htdocs\psisecurite\system\libraries\Templ ate.php on line 174

I have installed the DC_DynamicTable extension, but it is teh same thing with a test site without this extension

Is there a mistake in the configuration of my site ?

In another hand, I haven't see anythings to disabled formfield or to initialize checkbox field with a php file (but I found for a textfield with the tag {{get::somevariable}} ...

Thanks for helping and sharing
