[Resolved] Website Critical Error While Editing HomePage

[Usman]

Hey everyone, I am working on an e-commerce store: kaptaanchappal.com.

The site is working fine but when I try to edit the home page (https://kaptaanchappal.com/wp-admin/post.php?post=899&action=edit) it shows an error.

I haven’t found any email in the inbox. All other pages are editable except this. Anyone can guide me on this?

Looking Forward,
Usman

Hi there,

ask your host to enable debugging, they should then be able to provide a more detailed error log which can be used to diagnose the issue.

Hi @David thanks for replying.

I got the log file errors:

Fatal error: Uncaught Error: Call to a member function is_type() on null in /home/rapixqxb/kaptaanchappal.com/wp-content/themes/generatepress/functions.php:135 Stack trace: #0 /home/rapixqxb/kaptaanchappal.com/wp-includes/class-wp-hook.php(309): {closure}(‘Select options’) #1 /home/rapixqxb/kaptaanchappal.com/wp-includes/plugin.php(191): WP_Hook->apply_filters(‘Select options’, Array) #2 /home/rapixqxb/kaptaanchappal.com/wp-content/plugins/woocommerce/includes/class-wc-product-variable.php(60): apply_filters(‘woocommerce_pro…’, ‘Select options’, Object(WC_Product_Variable)) #3 /home/rapixqxb/kaptaanchappal.com/wp-content/plugins/woocommerce/packages/woocommerce-blocks/src/StoreApi/Schemas/V1/ProductSchema.php(477): WC_Product_Variable->add_to_cart_text() #4 [internal function]: Automattic\WooCommerce\StoreApi\Schemas\V1\ProductSchema->get_item_response(Object(WC_Product_Variable)) #5 /home/rapixqxb/kaptaanchappal.com/wp-content/plugins/woocommerce/packages/woocommerce-blocks/src/BlockTypes/AbstractProductGrid.php(104): in /home/rapixqxb/kaptaanchappal.com/wp-content/themes/generatepress/functions.php on line 135

My hosting providers asked me to consult with the theme providers.

Looking Forward,

[David]

If you look at the error stack, the last line points to:

wp-content/themes/generatepress/functions.php on line 135

So thats line 135 of the Themes functions.php file.
But as you can see here:

https://github.com/tomusborne/generatepress/blob/master/functions.php

The themes functions.php has only 122 lines. Which means that your functions.php has been modified on your site.
And i assuMe its the code that has been added there is breaking your site.

Can you remove any additional code ?

[Usman]

The rest of code is:

function wplook_activate_gutenberg_products($can_edit, $post_type){
	if($post_type == 'product'){
		$can_edit = true;
	}
	
	return $can_edit;
}
add_filter('use_block_editor_for_post_type', 'wplook_activate_gutenberg_products', 10, 2);

add_filter( 'woocommerce_product_add_to_cart_text', function( $text ) {
	global $product;
	if ( $product->is_type( 'variable' ) ) {
		$text = $product->is_purchasable() ? __( 'Size', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
	} else {
                $text = $product->is_purchasable() ? __( 'Buy Now', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
        }
	return $text;
}, 10 );

135 line is
if ( $product->is_type( 'variable' ) ) {

You will need to remove your custom code so the function.php file is exactly the same as the original file:
https://github.com/tomusborne/generatepress/blob/master/functions.php

Your filter code above can be added using one of these methods:

Thanks, @Leo for the recommendation. I did it and now getting this error:

Hi Usman,

To clarify, if you temporarily disable/remove this code you have here: https://generatepress.com/forums/topic/website-critical-error-while-editing-homepage/#post-2269446, does the error still exist?

Kindly let us know.

[Usman]

Hey @Fernando, thanks for the suggestion.

If I remove the code, it works fine. I was wondering if there is a way I can keep this code!

For now, I removed it.

[David]

Try changing this:

add_filter( 'woocommerce_product_add_to_cart_text', function( $text ) {
	global $product;
	if ( $product->is_type( 'variable' ) ) {
		$text = $product->is_purchasable() ? __( 'Size', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
	} else {
                $text = $product->is_purchasable() ? __( 'Buy Now', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
        }
	return $text;
}, 10 );

to:

add_filter( 'woocommerce_product_add_to_cart_text', function( $text ) {
        if ( is_admin() ) {
            return; 
        }
	global $product;
	if ( $product->is_type( 'variable' ) ) {
		$text = $product->is_purchasable() ? __( 'Size', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
	} else {
                $text = $product->is_purchasable() ? __( 'Buy Now', 'woocommerce' ) : __( 'Read more', 'woocommerce' );
        }
	return $text;
}, 10 );

And please this article on how to add PHP to your site:

https://docs.generatepress.com/article/adding-php/

If you continue to add the code to the parent themes functions.php they you will not be able to update the theme without losing that code.

[Usman]

Thank you @David for your efforts.

I did the above and in this way, I can edit that page but when I view it, it shows an error.

It seems like I need to delete that code only.

[David]

Are you using Woocommerce blocks on that page ?

[Usman]

Hey everyone, pardon me for the late reply.

I removed the code and everything is working fine. I can bear this.

But, can you guys assist me in setting up my homepage properly?

I want to display products category wise as https://kaptaanchappal.com but the problem is, the previous imported settings look nice but I tried the Woo widget at down that is not appealing much.

How can I display the products are GP does but category wise?

Will be thankfull.

[Leo]

Can you open a new topic for the separate question?

I’ll mark this one resolved.
