Flow-Flow got invalid data from server

Greetings,

I have WP WordPress 4.9.8, PHP 7.0.30, Memory Limit 256M and Upload Max. Filesize 128M checked all in green in the plugin’s main page.

I have a page created with WP Page Builder 5.5 (most recent) and when adding a GRACE stream and get following message:

Warning: Your project already makes use of Composer. You SHOULD use the composer dependency “phpfastcache/phpfastcache” instead of hard-autoloading. in /home/annapgreen/public_html/web/wp-content/plugins/insta-flow/libs/phpFastCache.php on line 59

They are all warning, but the feed still does not display.

I have updated everything and do not know what can be wrong.

Any help will be greatly appreciated.

Best,
