With the seobility seo check I see the generator that my website uses, which is not bad in itself, but it can be useful for any interested people to know which script I use. Is there a way to hide this as well as change the cookie name to the website name and not osclass?

Right now you can achieve that just by updating core.

Not sure what you mean by that.. I am already using latest v8.0.0.

In oc-load.php (root folder).

Find this function:
function osc_meta_generator(){
  echo '<meta name="generator" content="Osclass ' . OSCLASS_VERSION . '" />' . PHP_EOL;
}
and comment echo, change it, or add return false; at start of function, or keep it as blank function.
