Just clicked an activation link for a new user, and got this error……

[Bret]

check the activation link below

[Tom]

Hi there,

None of the WooCommerce module functions should be firing unless WooCommerce is installed and activated.

Can you confirm that this site has WooCommerce activated already?

[Bret]

Yup, it’s activated…..

it is a multisite instance, but yeah its a shop demo site so its definitely activated.

[Tom]

Hmm, so is_checkout() should be defined.

Is WooCommerce network activated? What about GP Premium?

This could explain it: https://core.trac.wordpress.org/ticket/23197

[Bret]

This could explain it.

Currently neither GP Premium or WooCommerce are network activated but I might have changed the GP Premium config as I flailed about awkwardly trying to fix the problem.

What is the recommended configuration then? Sorry that’s not clear…..

[Tom]

I’m more curious than anything at this point – multisite can be very weird.

What happens if you network activate WooCommerce? Does the error go away when activating GPP?

[Bret]

OK will try a few variations and see if it makes any difference

[Pierre]

Hello,

I have the same problem here. On a site in production, it’s quite annoying.

@Tom is it possible to add a

if( function_exists( 'is_checkout' ) )

in /gp-premium/woocommerce/functions/functions.php:450 ?

Thanks

[Tom]

We can absolutely do that, but that would mean adding checks like that to a lot of different areas in our WooCommerce integration.

Technically, none of that code should fire at all if WooCommerce isn’t activated. Are you using multi-site as well? Is the error happening on a site that has WooCommerce activated?

[Pierre]

Hi Tom,

It’s a multisite with subdomains installations.

Site 1 : main.domain.com, GP premium activate, Woocommerce deactivate.

Site 2 : other.domain.com, GP premium activate, Woocommerce deactivate.

Site 3 : shop.domain.com, GP premium activate with Woocommerce module, Woocommerce activate.

The user has created an account on the shop.

The activation link seems correct, like :
https://shop.domain.com/wp-activate.php?key=7uj7607e88bf7c88
But arrives on a fatal PHP error.

Strange bug. Later I will do more tests.

[Tom]

Very strange, indeed.

We’ll make a note to add this check to GPP 2.3.0.

Can you confirm that adding the check in that one place fixes the issue if you change your file to include it?

[Pierre]

Hi Tom,

Here are the changes I had to make to avoid a PHP fatal error:

function generatepress_wc_checkout_sidebar_layout( $layout ) {
  
  if( ! function_exists( 'is_checkout' ) ) {
    return $layout;
  }

function generatepress_wc_show_sticky_add_to_cart() {

  if( ! function_exists( 'wc_get_product' ) ) {
    return;
  } 

function generatepress_wc_scripts() {

  if( ! function_exists( 'is_checkout' ) ) {
    return;
  }

function generatepress_wc_checkout_footer_widgets( $widgets ) {

  if( ! function_exists( 'is_checkout' ) ) {
      return $widgets;
  }

I think it’s a bug in the WordPress core. I created a plugin that registers a “random_test()” function, and is only activated on the shop site. In another plugin, I have an filter on the WordPress hook “body_class”. In the function called by this filter, I call random_test(). This also causes a PHP fatal error on wp-activate.php. So wp-activate.php does not load the plugins correctly.

[Tom]

Thanks for that! This has been implemented in GPP 2.3.0.
