A simple debug log plugin. Check Debug Log from the dashboard. Enable and disable Debug ( ‘ WP_DEBUG’, ‘WP_DEBUG_LOG’, ‘SCRIPT_DEBUG ‘ ) with one click. Insert new Constant Item in the config file without editing it directly.
Just Download and activate the plugin. Then go to Tools -> WP Debug Log
it's exactly what i am after for. instead of connecting to ftp, opening wp-config.php, editing the constants, saving, uploading, reloading site, opening debug.log and deleting it and so on … you simple enable the toggle and look into the logs right in wordpress with nice styling so you can easily distinguish between warning and errors.
in the future i would like to see more toggles for instance for WP_DEBUG_DISPLAY. for some reason this is missing?!
