Debugging
Freemius has inbuilt options for debugging and logging issues so as to make the integration process easier for developers. Here is how to enable and use these features:
Access the Freemius Debug Page
You can access the Freemius Debug page directly via {domain}/wp-admin/admin.php?page=freemius to get information about the active SDK, Freemius-powered products on the site, users, and more.
Setting WP_FS__DEV_MODE to true will enable logging. It will automatically activate the logger that outputs all logs to your browser's debugging console.
Output Logs to Screen
You can output all logs to the screen by adding &fs_dbg_echo=true to the query string.
Adding fs_dbg_echo=true to the query string will only work when Freemius is set to development mode. Therefore, websites using your product are not at risk of exposing the logs unless an administrator sets WP_FS__DEV_MODE to true or manually toggles on the debugging switch in the Freemius Debug page.
Debug Bar Integration
Additionally, if you are using Debug Bar, Freemius SDK logging is fully integrated with it to make debugging even easier with its UI.
