    Default EFG Module: Warning too few arguments

    Hello,
    I am using contao 2.10 and I've recently installed efg extension.

    When I want to see Form data, there are 2 warnings and i can't see the data. The warnings are the following:

    1) vsprintf() [function.vsprintf]: Too few arguments in ...\system\drivers\DC_Formdata.php
    2)Cannot modify header information - headers already sent by (...\system\functions.php:164) in ...\system\libraries\Template.php

    The first warning seems to be a problem with the label's lenght. The error comes from this section of the DC_Formdata.php file:

    Code:
    // Shorten label it if it is too long
    
    				$label = vsprintf((strlen($GLOBALS['TL_DCA'][$this->strTable]['list']['label']['format']) ? $GLOBALS['TL_DCA'][$this->strTable]['list']['label']['format'] : '%s'), $args);
    
    
    
    				if (strlen($GLOBALS['TL_DCA'][$this->strTable]['list']['label']['maxCharacters']) && $GLOBALS['TL_DCA'][$this->strTable]['list']['label']['maxCharacters'] < strlen($label))
    
    				{
    
    					$this->import('String');
    
    					$label = trim($this->String->substrHtml($label, $GLOBALS['TL_DCA'][$this->strTable]['list']['label']['maxCharacters'])) . ' …';
    
    				}
    I was looking for this error on the web and there are some solutions, but they don't work for me. I also use characters like % () and /on the labels but I removed them and the problem is still there. Does anybody knows if there is a maximum number of characters for the labels? some of my labels are a bit long 30 or 40 characteres.

    Default Re: EFG Module: Warning too few arguments

    I've solved the problem, it's not possible to write the % symbol in the field name.

    Thank you!
