Dear
prntscr.com/ipzj24
you can use include instead of require_once in
please go to /modules/mod_sj_k2_gridslider/core/helper.php and find
require_once(JPATH_SITE .'/components/com_k2/helpers/route.php');
require_once(JPATH_SITE .'/components/com_k2/helpers/utilities.php');
=> change to:
include(JPATH_SITE .'/components/com_k2/helpers/route.php');
include(JPATH_SITE .'/components/com_k2/helpers/utilities.php');
If it still have error
Please send us the pass ftp account again, i will check directly for you
thanks
