Hi Israel ,

You can edit them in code at:

\ Root \ themes \ name_theme \ teamplate \ index.tpl

Delete

{hook h="testimonials"}
              
            {if $page.page_name=='index' && isset($HOOK_SMARTBLOGHOMEPOST) && !empty($HOOK_SMARTBLOGHOMEPOST)} 
             {$HOOK_SMARTBLOGHOMEPOST nofilter} 
            {/if}

and

\ Root \ themes \ name_theme \ teamplate \ layouts \ layout-both-columns.tpl

Delete

{if isset($HOOK_FIELDBRANDSLIDER) && !empty($HOOK_FIELDBRANDSLIDER)}
            <div class ="Brands-block-slider">
            <div class="container">
                {$HOOK_FIELDBRANDSLIDER nofilter}
            </div>
            </div>
        {/if}

Or you can uninstall those modules. For example removing "fieldtestimonials", "smartbloghomelatestnews", "fieldbrandslider"
