i spent some hours but the solution is soo simple and unbelievable.
Search in the bootstrap theme under includes for the form.inc file. In this file all fields are overwritten with . So the homebox is searching for an action and a input field but don`t find anyone. If you replace the else return value in this query:
if (isset($element['#id']) && in_array($element['#id'], $whitelist)) {
return '<input' . drupal_attributes($element['#attributes']) . ">\n"; // This line break adds inherent margin between multiple buttons
}
else {
return '<button' . drupal_attributes($element['#attributes']) . '>'. $label ."</button>\n"; // This line break adds inherent margin between multiple buttons
}
with this: return '<input' . drupal_attributes($element['#attributes']) . ">\n"; // This line break adds inherent margin between multiple buttons
you`ll get working the homebox.
