I added in a site an external lib that called via script inclusion, that is a js that made the communication with the services that this company offered. After that they added the information on the page.
So far so good, but now the contract has been terminated and I've removed the inclusion of this external js, but I do not know how it is still loaded on the site, it's like a cache but it does not make sense, since I removed the inclusion of this script, why and how to solve it?
