This solution will describe how you can remove the 'Powered by' text from ChronoForm v.1.2. This ChronoForm version requires subscription to remove the 'Powered by' however you can use most of the functionality and also remove the wordings 'Powered by'

Here is how:

1) You will need to locate a function call eval() in the file chronocontact.html.php

eval(base64_decode('JGRvY3VtZW50ID0mIEpGYWN0b3J5OjpnZXREb2N1bWVudCgpOw0KJGRvY3VtZW50LT5hZGRDdXN0b21UYWcoJGhlYWRlcl9jb2RlKTsNCmVjaG8gJE15Rm9ybS0+YWRkaGFzaCgpOw=='));

2) Remark the function call eval() by adding //

3) This function actually executing following three line code which is encrypted. Once you are commenting the eval() function you must need to put the code which is executed by eval() function. In this case code will be:

	$document =& JFactory::getDocument();
	$document->addCustomTag($header_code);
	echo $MyForm->addhash();

4) Now you know what was the encrypted code that was executing. You now need to check out the fuction defination for addhash(). You will be able to find this fuction defination in the file 'choronoform.php'

5) addhash() function returns either ' ' or it returns some encrpted code. You will replace the encrypted code with blank string ' ' i.e. function should return  ' ' in both parts of if condition
