форма поиска закрывается после нажатия в поле формы

Привет дорогие программисты и гении PHP,

Я новичок в php и запустил форму поиска на моей странице магазина WordPress (которая еще не опубликована). После поиска ошибки в течение нескольких дней я все еще не понимаю, где ошибка может быть. Я установил SublimeText + SublimeLinter, чтобы найти синтаксическую ошибку, но, видимо, ее нет …

Форма поиска закрывается, как только я пытаюсь что-то набрать (как только я нажимаю на нее).

Я использую тему мистера Тейлора: http://themeforest.net/item/mr-tailor-responsive-woocommerce-theme/full_screen_preview/7292110

Итак, вот код (он довольно длинный, и я не уверен, поможет ли он сам по себе, поэтому, пожалуйста, дайте мне знать, если мне нужно что-то добавить):

<?php global $woocommerce, $mr_tailor_theme_options; ?>

<footer id="site-footer" role="contentinfo"><div id="own_footer">
<img src="../../image_assets/logo_footer.png" alt="Logo">

Странно также то, что этот код взят из footer.php, но все же, по-видимому, влияет на панель поиска ….

Я знаю, что это похоже на ловлю динамита, но у меня просто закончились идеи. Так что спасибо всем заранее!
