404 Not found on all my product pages

[animes-pro]

Hi, can someone assist me? I found that there are 404 - not found message on all of my online store product pages. Please take a look at the picture below.

May I know how can I make it disappear? Is it related to the outdated apps? I am looking forward to your responses. Thanks.

Here is my website. animes-pro.com

Hi there @animes-pro!

I took a look around your store using the link you shared here, and I was able to navigate my way to this product page, which is showing up okay for me from my location here.

Could you check this out with me and maybe share a link or two to affected products on your end so we can check these out together?

You mentioned that this might be related to some apps you had on your store, would you have previously added apps to your store that would have added some code to your theme or product pages specifically? 

If so, you may need to remove any code leftover by these apps in your theme code in order to ensure proper functionality.

Feel free to share any affected product links with me here so we can look at some more examples and let me know about any apps you may have added to your theme so we can check this out for you here.

Are you looking to sell internationally at all, or do you just work within your domestic market?

Let me know if there's anything else you need to work on for your store or business at the moment.

Regards,

Don

Hi Don,

Thank you for your reply. Here is the affected product pages.

I have added several apps that require adding code to my store. I am afraid that I don't know exactly which apps caused the problems.

Now, we work within our domestic market. We may ship internationally only by request.

@animes-pro   you can update the app first else remove the app code from the theme file.
