Hi,

thank you for this awesome plugin. But, I have a problem the I put this code in the functions.php to follow the “timings” in my web.

// Start the ‘foo’ timer:
do_action( ‘qm/start’, ‘foo’ );

// Run some code
my_potentially_slow_function();

// Stop the ‘foo’ timer:
do_action( ‘qm/stop’, ‘foo’ );

The web just crash.

Is it correct the code? In this way I can’t check the performance of my web.

Thank you

Regards

Yes that’s correct. Are you able to check your PHP error log to see what the error is?

Also, the plugin crash when I modify the products in woocommerce.

This is the error when I modify the products in woocommerce:

Fatal error: Uncaught Error: parse_url() expects parameter 1 to be string, null given
in /home/customer/www/altaico.es/public_html/wp-content/plugins/query-monitor/collectors/http.php on line 374

And this is the error when I add the code for timings:

my_potentially_slow_function is just some example code, you should replace this with the code that you’re trying to profile.

Understood, I would like to check what functions slow down the website.

For example, the timer stars a when the page is loaded, Query Monitor records the page generation time and check what slow down it.

Can you help me?

Please and thank you.
