i can not change url

What is the link to your site and can you please confirm that your account has administrator level access?

WordPress 4.4 have all these but you need to have admin user to access this .

the link is https://www.monscientific.com/wp/ please, i can not get what you mean by administrator level access.

Who can assist me? My easy slider is not working on wp4.4. when i go to plugin customization, i can see it working but not on the home page.

Is the plugin “Easy Slider” or “PE Easy Slider”?

Also, did you resolve the earlier issue?
