Hi @webzang,
Indeed, the problem is not from the Pre-Order plugin, but a custom code added to that template that uses functions of the Pre-Order plugin incorrectly.
To fix the issue, replace this part:

foreach( $available_variations as $i => $variation ) {
    $id = $variation['variation_id'];
    if ( class_exists( 'YITH_Pre_Order_Product' ) ){
        $pre_order = new YITH_Pre_Order_Product( $id );
        if ( $pre_order->get_pre_order_status() == 'yes') {
            $available_variations[$i]['availability_html'] = 'Pre-order';
        }
    }
}

with this:

if ( class_exists( 'YITH_Pre_Order_Utils' ) ) {
    foreach( $available_variations as $i => $variation ) {
        if ( $variation instanceof WC_Product && YITH_Pre_Order_Utils::is_pre_order_active( $variation ) ) {
            $available_variations[$i]['availability_html'] = 'Pre-order';
        }
    }
}

Hi @remowebdesigns,
It’s hard to know why this error is being produced, there is little information.
Maybe it is a conflict with some other plugin that manages capabilities. I suggest you test by deactivating all plugins except WooCommerce and YITH WooCommerce Subscription. If the problem is gone, then you should activate the plugins back one by one until you find the one that is producing the problem.

Hi @gerd_e,
Thank you. You can fix the style issue with a CSS code like this:

.woocommerce.ywraq-wrapper .ywraq-form-table-wrapper.wide {
    align-items: normal;
}

.woocommerce.ywraq-wrapper .ywraq-form-table-wrapper.wide .yith-ywraq-mail-form-wrapper {
    padding-top: 0;
}

Hi @webmastertsd,
As explained, YITH Request a Quote for WooCommerce doesn’t include such an email for the customer. This feature is available in the commercial version.

Hi @gerd_e,
Unfortunately, I cannot help you if I cannot see the website and the HTML code.
Please note this is more of a problem with the Impreza theme due to its CSS styles.

Hi @elito-1,

Hi @anh2phat,
You are talking about the commercial version of the plugin. This Support Forum is exclusively for the free version.
To get assistance, please submit a support ticket at yithemes.com. Thank you.

Hi @pasamsin,
In the shop page, there is no indication on variable products that any of their variations is a pre-order product. I’m sorry, but the plugin doesn’t include such a feature.
