I updated my wordpress website and i must have pressed the wrong button along the line as I lost all access to my dashboard, all the administrators did.
I am not sure what version it is, I assume the latest
but when i try to enter the dashboard I get the :
Call to undefined function wp_is_mobile() in /home/content/61/7305561/html/yes2pets/1/wp-admin/index.php on line 24
What can I do?
Thank you so much for your time and help,
