Uncaught Error: Cannot use object of type WP_Error as array

Hello,

I have this error when visiting /wp-admin/ and page returns 504 sometimes. Then error text from wordpress recovery mail.

POST SMTP uses Freemius to load add-on information from remote server (https://api.freemius.com/v1/plugins/10461/addons.json?enriched=true&count=50&sdk_version=2.5.5) which is triggered on “do_action(‘admin_menu’)”.

I think it is better to load add-on information using wp-cron instead of “admin_menu” hook. Because wp-cron can run longer without returning 504 timeout error and add-ons are not critical to load when site administrator tries to manage wordpress.
