Hi @Vincenzo.M,
Sorry for the delay in replying.
That view that you are seeing is not meant to be accessed directly. It is there to be used by classic view that uses the legacy rendering mechanism.
The SuiteCRM 8 app should be available in /public (according to the url you have in the previous screenshot)
Do you get a blank page when accessing /public?
If so, it maybe a misconfiguration in mod_rewrite, please consider having a look at the following post
