My hosting provider and develpor guided me and gave me a hint to inform you, see these screenshots > https://prnt.sc/vbwxqe . https://prnt.sc/vbx165 . https://prnt.sc/vbx77h etc.
This thread with the related issues is given by my hosting provider Vimexx.nl: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Not_a_function
I activate cache plugin or not but these errors remains unchanged in searchh console, https://prnt.sc/vbx9rh etc
Homepage showing Like this during live inspection, https://prnt.sc/vbxc0l
Note: Sometimes during working hours every day these issues in search console decreases. As these changes everytime so at one moment i thought for a WHILE maybe someone else hacked my website and making changes :). So for sure i changed all password, mysqyl, php admin, wp admin and direct admin. But same issues are still their.
