Console shows a JavaScript error on your product page, which is related to Swiper framework, which seems to be a part of your theme. You need to contact either the theme developer or whoever had added that custom script (if its not from the theme).

SSL Labs still shows the same cert for your site:

There are some online guides you could google up, like

But things may depend on the environment of your hosting.

Looks like you use Jetpack and images are being served from a WordPress.com server.

Example of URL:

https://i0.wp.com/elliestravelobsession.com//wp-content/uploads/2019/01/IMG_20180615_133647503_HDR-e1547751417427-768x1024.jpg

Note the i0.wp.com in the beginning.

I am not familiar with Jetpack as I never used it, but have you tried disabling it? Or maybe there are some options you could tinker with.

There are mail logging plugins which save all outgoing emails and allow to resend them if/when needed. Put “mail log” into the search bar above and explore your options.

What you see in the Woocommerce core files is a support for this deprecated method (thats why it only gets a notice, not error). However they are being triggered by something which actually uses that, and judging by logs, it is probably something that adds code to your product tabs. Your theme, a plugin, or some custom function.

There are some weird redirects, which forward the visitor to another page when “adding to cart” (and instead of it). It is very likely that there are some other customizations of standard store processes, which could be the reason for errors on checkout, you probably need to contact whoever had made these customizations for you.

If you have some customers which are cooperating, you need to ask them to record the issue with smartphone or screen video capture. Also turn on the debug mode and check logs for errors. You could as well try a service which provides recording of users’ behavior on your site, some offer free trials and/or limited free plans for that.

What are these suppliers in terms of data, how are they defined in your store? If that depends on the products (categories or ids) in cart, you could work through it and turn off the non-matching shipping method basing on the cart contents.

It also does not load in Safari on Mac. You have some weird SSL certificate, “issued by CPanel”, and that would probably be the reason. Try switching your site to a Let’s Encrypt certificate, which can be obtained and renewed for free.

Woocommerce by default does not allow to add orders from the past to a newly registered account. Custom extra code of course could make it possible, but looks like it is not the case with this MailChimp plugin, however for some reason it assumes such possibility.

So if the user does not have a registered account, then orders can not be possibly seen in “my account” later – since when you register through the link, you get a brand new clean account, and the order number in the link is not connected to it.

This is some wrong design of the MailChimp plugin, it should either auto-connect unregistered orders upon registration for customers who visit this link, or avoid sending such links to non-registered buyers.

Do you use a translation plugin, like Loco Translate? If that text is within a translatable set, you could change it this way. Either that, or digging into Yoast code, or asking Yoast support.

The stock status dropdown is in effect even if manage stock checkbox is not checked. Do you have the default variation selected?

If that is not the issue in your case, more detailed info would be needed to help.

Check whatever is made with Visual Composer in the product page: its section is “covering” the upper half of the product page so it is unclickable. Probably some layout settings of this section are wrong.

Have you tried switching to default theme like Twenty Seventeen and checking the code?

Woocommerce does not add Open Graph, if it is not your theme, then it could be some SEO plugin.
