 * Hi,
    I just uploaded to version 1.5.3 . In a checkbox profile option, I have 
   this error:
 * Warning: preg_replace(): Unknown modifier ‘c’ in /home/website/public_html/wp-
   content/plugins/buddypress-multilingual/includes/class.xprofile.php on line 192
 * The same text appears in back-end and front-end (edit profile section)

 * Found the problem.
 * I had in textboxes choice options a “/”. Just removed it and error disappear!
   I supposed it was read as RegEx instruction.

 * I fix it without change the option’s text.
 * Just modified row 192 in file _class.xprofile.php_ with:
 *     ```
       $name = str_replace("/", "\/", $option->name);
       return preg_replace( "/\>{$name}\<\/label\>/", ">{$label}</label>", $html, 1 );
       ```
