Http internal links in page source.

[netamis]

I have an issue with moving from http to https. On the logo link and on the add button link there are still the http links instead of http. 

examples, as are shown in the main page source: 

logo:

<div id="header_logo"> <a href="http://www.rock4u.ro/" title="Rock4U SHOP">

add button link:

<div itemprop="offers" itemscope itemtype="https://schema.org/Offer" class="content_price"> <span itemprop="price" class="price product-price"> 125,00 Lei </span><meta itemprop="priceCurrency" content="RON" /></div><div class="button-container"> <a class="button ajax_add_to_cart_button btn btn-default" href="http://www.rock4u.ro/cos?add=1&amp;id_product=2910&amp;token=d5497c0749a05580408cda56238a5876" rel="nofollow" title="Adauga in cos" data-id-product="2910">

update:

For header logo link on header.tpl :

 

<div class="container">

                            <div class="row">

                                <div id="header_logo">

                                    <a href="{$base_dir}" title="{$shop_name|escape:'html':'UTF-8'}">

                                        <img class="logo img-responsive" src="{$logo_url}" alt="{$shop_name|escape:'html':'UTF-8'}"{if isset($logo_image_width) && $logo_image_width} width="{$logo_image_width}"{/if}{if isset($logo_image_height) && $logo_image_height} height="{$logo_image_height}"{/if}/>

                                    </a>

                                </div>

                                {if isset($HOOK_TOP)}{$HOOK_TOP}{/if}

                            </div>

So it looks like the variable: {$base_dir} is http instead of https. The $logo_url is correct, using https.

Any idea how those can be fixed?
