Fatal error: mb_detect_encoding() does not exist
-
We use PHP 5.5. After I activate the plugin, I get a PHP Fatal error: function mb_detect_encoding() does not exist when I try to edit the form or view the form on a page. I did a google search and it looks like this error occurs because I do not have multibyte string extension enabled. Is this function absolutely necessary or is it possible to do a check if the function exists before using it? There is another plugin which provides the same functionality, but I’d rather use your plugin because I think yours is better supported.
Thank you.
