OK, I got a fix from X-Cart:
Code:
Please download X-Cart 3.5.14 distributions and open the 'admin/category_modify.php' file. Then copy the lines
define('USE_TRUSTED_POST_VARIABLES',1);
$trusted_post_variables = array("category_lng_description","category_new_description","description");
from the new version of the file to yours.
So, use the new prepare.php but add the lines above (taken from the top of a 3.5.14 category_modify.php) to your exisiting
category_modify.php ...seems to do the trick
