[Resolved] Exception "invalid product" in generatepress_wc_show_sticky_add_to_cart()

[healthandbeauty]

If the GP Premium sticky add to cart functionality is enabled, we got a log of “Invalid Product” exceptions while browsing static pages. The problem comes from line 1069 in the woocommerce\functions\functions.php. If you move the is_singlar or/and the generatepress_wc_get_setting( ‘sticky_add_to_cart_panel’ ) in front of the $product = wc_get_product( get_the_ID() ); line. The error is gone.

Best regards

And this is happening when you visit standard pages? What about when you visit products?

Thanks for the info! We’ll get it sorted 🙂

[healthandbeauty]

Hi Tom,

sorry was in holidays the last days.

This error happens if I visit “standard” pages, eg. Shipping, Payment information pages. There is no error on products.

Best regards
David

[Tom]

I can’t replicate this at all for some reason.

Does it happen if you deactivate all of your other plugins?

[healthandbeauty]

Hi Tom,

my bad. The error was shown due to a xdebug setting in my php.ini.

xdebug.show_error_trace = 1
xdebug.show_exception_trace = 1

Best regards
David

[Tom]

Glad you figured it out 🙂
