Please fix the form errors.

You are using the WP Fastest Cache plugin. Have you tried flushing the cache?

Actually, this is happening because something is modifying the HTML of the name attribute of the input field of the title in the form.

The input field HTML should look like this:

<input
    type="text"
    class="input glsr-input glsr-input-text"
    id="glsr_b3a4ad81-title"
    name="site-reviews[title]"
    required=""
    placeholder="Summarize your review or highlight an interesting detail"
    value=""
>

The one in your review form looks like this:

<input
    type="text"
    class="input glsr-input glsr-input-text"
    id="glsr_b3a4ad81-title"
    name="site-reviews<div class=&quot;container section-title-container&quot; ><h3 class=&quot;section-title section-title-normal&quot;><b></b><span class=&quot;section-title-main&quot; >Lorem ipsum dolor sit amet...</span><b></b></h3></div>"
    required=""
    placeholder="Summarize your review or highlight an interesting detail"
    value=""
>

Perhaps you have added an invalid code snippet somewhere?

Thanks,

by disabling other plugins one by one we found out that this is happening only when the plugin “Booster for Woocommerce” is activated.

We contacted their support now.

Try disabling all the boosts you have enabled, then reenable them one by one to find out which one is responsible. If you can track it down, let me know here.

You might also want to check if you are using a caching plugin. If so, try flushing the cache.

I already tried that and also did a reset of all the booster plugin settings to default and it didn’t help. So it happens just by having the default booster plugin installed without any additional configuration done to it.

I installed the Booster plugin and do not see this problem in the form, so something else must be going on here. Are you using any custom Code Snippets that are misbehaving?

Using this one snippet which hides the add to cart button in a specific category. I tried disabling it but didn’t help.

function hwn_is_purchasable($product_purchasable,$product) {
    if( has_term( array('pletene-z-papiera'), 'product_cat', $product->id ) ) {
        return false;
    }
    return $product_purchasable;
}
add_filter('woocommerce_is_purchasable', 'hwn_is_purchasable',10,2);
