1.3 meta-tags don't show up! Help needed

[berlin030]

hello,

i am using prestashop 1.3 and i am having big trouble, as my meta-descriptions and keywords do not show up in the headers of all pages.
here is what my header.tpl says:

{if isset($meta_description) AND $meta_description} {/if} {if isset($meta_keywords) AND $meta_keywords} {/if} {if isset($css_files)} {foreach from=$css_files key=css_uri item=media} {/foreach} {/if} {if isset($js_files)} {foreach from=$js_files item=js_uri} {/foreach} {/if} {$HOOK_HEADER} {if !$content_only}
• {l s='This shop requires JavaScript to run correctly. Please activate JavaScript in your browser.'}
{$HOOK_TOP}

{$HOOK_LEFT_COLUMN}
{/if}

Thank you for helping.

Best
Martin
