I am receiving a fatal error that is killing my custom tab.

Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /nfs/c07/h02/mnt/111140/domains/whirlwindpropellers.com/html/airboats/wp-content/plugins/woocommerce/templates/single-product/tabs/tabs.php on line 42

code for functions.php:
```
add_filter( 'woocommerce_product_tabs', 'woo_rename_tabs', 98 );
function woo_rename_tabs( $tabs ) {

$tabs['description']['title'] = __( 'Installation Instructions' ); // Rename the description tab

return $tabs;

}

add_filter( 'woocommerce_product_tabs', 'woo_reorder_tabs', 98 );
function woo_reorder_tabs( $tabs ) {

$tabs['additional_information']['priority'] = 5; // specs first
$tabs['description']['priority'] = 10; // installation instructions second

return $tabs;
}
```
Codein tabs.php where there error message is telling the problem is:
<?php call_user_func( $tab['callback'], $key, $tab ); ?>

I am stumped on how to get this tab working again. Could anyone point me in the right direction? Thank you very much in advance!

Would you need a direct url for the site this is happening on?

sure, wouldn’t hurt — that snippet seems like from Woo docs https://docs.woothemes.com/document/editing-product-data-tabs/ so I think there isn’t something wrong with the plugin or WooCommerce itself

it is happening on all tabs that are being created by your plugin.

‘Installation Instructions’ tab.

Hey there

What happens if you remove the custom code? Does the plugin work as expected? If yes, there might be a problem with your current theme or the placement of your code.

Hey @BlacARTCreativeGroup, it looks like those tabs are all WooCommerce core tabs, and your code is only modifying WooCommerce core tabs. I’m going to resolve this since the code and the product page are not related to the Custom Tabs Lite plugin.

I’d recommend taking some steps such as deactivating all plugins except WooCommerce and switching to a default theme to determine if there is some other code interfering with this snippet. If not, the snippet itself may need an update, so I’d post this in the WooCommerce forum to see if they’ll update the documentation for it if you’ve determined that the snippet is indeed the issue.

thanks!
