Hello, @rodrigocarvalhomeloto,
Please go to Porto >> Theme License, unregister the theme license, and then re-register it using the same purchase code.
Next, head to Appearance >> Install Plugins and install and activate the plugins one by one. This should help resolve your issue.
If the problem persists, please share your site’s WP Admin URL and credentials in the private content area of this topic. This will allow us to take a closer look and assist you further.
Best Regards,
PThemes Team.
