Reloads to the top when i click Back button in safari browser from product page!

Hey there, @hassan024! Thanks for contacting us. I’m happy to help you.

This problem only occurs on iPhones using Safari or Chrome browsers

Can you please confirm if this is happening on Chrome on computers?

I just checked your website on Chrome on my computer and was not able to replicate the issue there.

The browser console suggests there’s an issue with the back/forward cache.

Do you have any caching plugins on your site?

I’d like to understand your site properly. Please share with us the necessary information below for us to investigate the issue further:

System Status Report which you can find via WooCommerce > Status > Get system report > Copy for support.
Fatal error logs (if any) under WooCommerce > Status > Logs. Then you can use the selector to search for Fatal Errors.
You could copy and paste your reply here or paste it via https://gist.github.com/ and send the link here.

Looking forward to your reply.

Have a wonderful day!

No, it's not happening on Chrome on computers; it's only happening when opening the website on an iPhone. Currently, I'm using the WP-Optimize plugin for caching.

Hi there @hassan024,

Thanks for sharing the system status report and the error messages.

Looking at the error message, it suggests that there’s an issue with the Woostify theme you’re using on your WooCommerce site. Specifically, it’s trying to call the get_cart_subtotal() function on something that isn’t defined or is null.

Could you try switching to a default theme like Storefront or Twenty Twenty-Four and see if the issue experienced on mobile persists?

Please be sure to make a backup of your site before proceeding.

Let us know how this goes.
