Stripe WordPress Plugin not working if Javascript is optimized

Here is a screenshot of the jQuery problems I found on the checkout page;

I hope it can help ??

ah, “jQuery is not defined”, in that case you add js/jquery/jquery.js to the comma-separated list of JS optimization exclusion ??

if that does not work, you can indeed excluded the checkout from autoptimization using the API. let me know if you want to go down that path (if excluding jQuery does not fix the problem).

Thank you for your advise!

By adding s/jquery/jquery.js I solved those jQuery mistakes, however I still receive a generic message that says that it wasn’t possible to complete the operation. I can’t find any real issue from the console so I guess excluding checkout page might be the best choice.

I forgot to tell you that my website is on http but checkout is done on https, does this influence somehow the procedure?

Thank you again for your support!

http vs https does not really make a difference for autoptimize, no.

maybe try excluding jquery AND stripe.js?

else you can exclude the checkout using this code (which assumes the URL contains ‘/checkout’);

add_filter('autoptimize_filter_noptimize','checkout_noptimize',10,0);
function checkout_noptimize() {
	if (strpos($_SERVER['REQUEST_URI'],'/checkout')!==false) {
		return true;
	} else {
		return false;
	}
}

You can use e.g. the code snippets plugin to add and activate this snippet.

Hey thank you so much for your support!

I am really appreciating it, I am in the middle of the tax season in my country, as soon as I am out of it I will definitely make a donation based on the instructions I found on your website.

I excluded both by writing stripe.js,js/jquery/jquery.js but it was still not working so I just used your useful code and excluded the checkout page, now the website is much much faster!

Thank you again for your precious support!

Hello again!

Right now everything is working fine, however there is a big difference between the results I got days ago from gtmetrix when I tested your plugin for the first time and the results I get now.

This is the result I got 2 days ago;
https://gtmetrix.com/reports/www.lovelymatcha.it/fZ4Vxw0X

Pagespeed 1.48 seconds | Page Size 1.42 | Requests 58

This is today;
https://gtmetrix.com/reports/www.lovelymatcha.it/uCKZts1r

Pagespeed 10.9 seconds | Page Size 1.41 | Requests 55

The only difference I see is that today the field DEFER PARSING OF JAVASCRIPT has a 0 score but 2 days ago it was 58.

Plus if I check the tab WATERFALL I notice that the first line takes 4.92 seconds to be downloaded and I can’t recognize what’s that, maybe the response time of the server?

Do you have any advise on how to solve the problem? The website is super fast now except for those 4-5 seconds in the beginning.

I even deleted and reinstalled it to see if I messed up something with settings.

Thank again you for your support!

PLEASE IGNORE MY REQUEST, I AM 100% SURE IT IS BECAUSE OF MY HOSTING PROVIDER.

Thank you!

well, there’s room for improvement in AO’s config;
* for “defer parsing”, try disabling “force JS into head”. you might have to “aggregate inline JS” as well and do some other tweaks.
* for the first line; this is the base HTML. I did a quick test on webpagetest.org and with approx. 130ms your “time to first byte” is very good actually
