How do I issue a warning in a wordpress plugin?
Simple, wherever you’re working on data that’s output, just use var_dump($whatever_variable). You can also use print_r($a_variable)
A more elegant way to handle notices/warnings
It is a good practice (and suitable for production) to log the errors, instead (or in addition to) displaying them. See Configure Error Logging in Codex. I usually combine it with my Error Log Dashboard Widget plugin for bit of UI on live servers.
WordPress is giving a warning but my code is working fine
I think ‘measurement_units’ => $ingredients, causes the problem, because the $ingredients is multi-dimensional array. You should use i.e. ‘measurement_units’ => $ingredients[0], or etc.. i think.

How can I get $wpdb to show MySQL warnings?
From quick look through the source it doesn’t seem like wpdb actively implements any handling for warnings (as opposed to errors). Proactively you can just ask for them as a custom query ($wpdb->get_results( ‘SHOW WARNINGS;’ ) I suppose, but implicitly they just aren’t tracked by WP core.
Default and warning messages & no login
Login to your C panel and in your site plugins folder, copy & cut the page-menu plugin and paste it to any other place in site directory, then refresh the site link. If it works then edit the plugin file name pagemenu.php and find the Pgm_Walker function and check the compatibility with Walker_Nav_Menu https://codex.wordpress.org/Class_Reference/Walker_Nav_Menu
