I received several questions about removing "ecommerce software by prestaShop" from classic theme footer section. In previous versions of prestashop (like 1.6 or 1.5) we just had to switch some option in shop back office.  In new PrestaShop 1.7 we must edit template file that is responsible for footer.

How to disable "Ecommerce software by PrestaShop"

We must edit theme file: /themes/classic/templates/_partials/footer.tpl - so please open this file and somewhere between lines 38 and 46 you should see code like below:

    <div class="row">
      <div class="col-md-12">
        <p>
          <a class="_blank" href="http://www.prestashop.com" target="_blank">
            {l s='%copyright% %year% - Ecommerce software by %prestashop%' sprintf=['%prestashop%' => 'PrestaShop™', '%year%' => 'Y'|date, '%copyright%' => '©'] d='Shop.Theme'}
          </a>
        </p>
      </div>
    </div>

If you want to remove "Ecommerce software by PrestaShop" - just remove code above. If you want to change it (for example add own copyright) just change this part:

            {l s='%copyright% %year% - Ecommerce software by %prestashop%' sprintf=['%prestashop%' => 'PrestaShop™', '%year%' => 'Y'|date, '%copyright%' => '©'] d='Shop.Theme'}

for exmaple:

            {l s='Template modification by Vekia :-)' d='Shop.Theme'}

After save you should not see this original text anymore. If you see it - this means that you need to clean cache in your shop.

How to remove the same text from order / checkout page?

You can do it in the same way. But in this case - we have to alter other file. File we need to edit is located in theme dir too. Exact path to the file is: themes/classic/templates/checkout/_partials/footer.tpl - please open it. You can find there code like i attached below. Exactly as previously - you can alter it or just remove it. Code to find below:

<div class="text-xs-center"> 2016 - CLASSIC - {l s='Ecommerce software by' d='Shop.Theme'} PrestaShopTM</div>
