my web has been giving me this warning since few months, and i have totally no idea how to repair it and what the posible reason can be.[https://deyizhiyizhi.com/](https://deyizhiyizhi.com/)
it keeps saying
Function create\_function() is deprecated in /home2/deyizhj1/public\_html/wp-includes/plugin.php
anyone has any idea?
thanks in advance!
