Woocommerce break wordpress backend with PHP 7.2

I have 2 WooCommerce sites running on PHP 7.2 so that is not your problem. Have you changed your theme to 2017 and then enabled WC? What theme are you using? What plugins are you using? You said you were moving to a more powerful VPS but do you have enough memory allocated to your site? Have you read the server requirements for WC 3.5.x?

Please don’t take offense at any of my questions but you may be so close to this issue that you are overlooking something.

What about your products? How many do you have? Are they variable products?

Had similar issues after updating the server to PHP 7.2 – in my case I fixed it by increasing the memory limit:

I used the first method – a new line in the wp-config.php file.

Just kept increasing the value until it worked.

Just tried to switch the theme to 2017 and still I face the problem. Remember the problem it’s in the backend and not in the front end, which is working fine.

I’m using Flatsome, updated to the last version.

Not many, I’m just using Woocommerce, jetpack, Contact form 7, Yoast, Really simple SSL. Of course I’ve already tried to disable every plugin and the only one that trigger this blank page is Woocommerce.

Yes, I’ve read the requirements and everything it’s okay from my side.

I have almost 50 products and are not variable products.

Please note, I’ve just downloaded woocommerce in one of those wordpress sites which are not a store and I face the same problem

I think I must say sorry, it’s not woocoommerce fault actually, but this plugin which usually is installed together woocommerce: YITH WooCommerce Wishlist
This is the real problem that make the backend crash

The funny thing is, if Wishlist is enabled and Woocommerce is disabled, everything works fine. If Wishlist is disabled and Woocommerce is enabled everything works fine. But if both of them are enabled, then the backend crash and gives me blank pages

Anyway fix it please, it’s an useful plugin

Hey @giggioman00

Happy to hear you found the cause of this, but I wanted to clear something up:

but this plugin which usually is installed together woocommerce: YITH WooCommerce Wishlist
This is the real problem that make the backend crash

WooCommerce never bundles another plugin with it. If you hear to the plugin page and download it or install via the plugins page on a fresh WordPress site, you will see that the YITH WooCommerce Wishlist plugin is not installed.

My recommendation would be to reach out to the YITH team and ask them to check this out.

As this isn’t a WooCommerce core plugin problem, I’m going to mark this thread as resolved.

Thanks,
