Call to undefined function _bootstrap_process_element() in /var/www/xxxxx/includes/form.inc on line 1870
We have form having upload elements. While uploading images, we are getting error: Call to undefined function _bootstrap_process_element() in /var/www/events/includes/form.inc on line 1870
Can anyone help to fix?
