Unable to navigate into the plugin settings, wizard, etc..

Hi,
since today I discovered I cannot surf in the plugin settings or wizard.

I can click on the admin left bar on compilanz and the dashboard is loaded, this is the only page that loads. If I click on integration or into the wizard button the URL change but not the page. The issue is present in two different websites.

I tried to deactivate, activate again the plugin, reinstall but the issue persist.
