If you have used the Types plugin in your Word Press site, you may come across this error:
"Warning: Missing argument 2 for types_render_field(), called in xxx.php on line xx and defined in..."
This is because the types_render_field now needs a second parameter which should be an array.
The parameters for field types:http://wp-types.com/documentation/functions/
The simple fix is:
Change this: "...types_render_field("xxx");"
To this: "...types_render_field("xxx", array('raw' => 'true'));"
Where "xxx" is your field name.
Happy coding!
