Expected behavior

Well, this bug could be fixed removing osc_ from oc-includes/osclass/install.php#L66:

$jsonLocales = osc_file_get_contents(osc_get_languages_json_url());`

To:

$jsonLocales = file_get_contents(osc_get_languages_json_url());`

I have identified the issue, a fix is ready will upload it asap. The issue is that the function using a constant which is not has been defined. 'file_get_contents' can cause other error as some host disable 'allow_url_fopen'.

Please test the latest release, I have successfully installed it on PHP 8.0 using docker.
