Hello again,
I did make a custom module with an image displayed, which I did publish in the modul position 'right'. I did test that in an iPhone 5 and when I did scroll to the bottom of the page, where the module ist displayed, I recognized, that a tip of my finger onto the image did lead to the login page of facebook or google+ depending on the position, where I did tap onto the image. Obviously the social share links are active in that region on the bottom (where the image in the custom module is displayed). This happens althought I did disable the social share icons in the settings of the template. There is nothing similar in the desktop-version: no linked area which points to facebook or any other social site. What to do to avoid that?
Best regards,
Christian
UPDATE: I did figure out that the 'invisible links' for social icons also are present in the desktop-layout - in my case they overlay the print/E-Mail icons at the right bottom of the page.

Dear C_Brand

You can remove it in
templates\sj_personal\index.php

<div id="socialShare">
<div class="itemSocialBlock">
<div class="post_social">
<a href="javascript:void(0)" class="icons-social social-fb" onclick="javascript:genericSocialShare('www.facebook.com/sharer.php?u=<?php echo JURI::current();?>&amp;url=<?php echo JURI::current();?>')" title="Facebook Share"><span class="nameSocial"><?php echo JTEXT::_('NAME_SOCIAL_FACEBOOK');?></span> <i class="fa fa-facebook" aria-hidden="true"></i></a>
<a href="javascript:void(0)" class="icons-social social-gp" onclick="javascript:genericSocialShare('plus.google.com/share?url=<?php echo JURI::current();?>')" title="Google Plus Share"> <span class="nameSocial"><?php echo JTEXT::_('NAME_SOCIAL_GOOGLE'); ?></span> <i class="fa fa-google-plus" aria-hidden="true"></i></a>

</div>
<script type="text/javascript">

window.open(url,'sharer','toolbar=0,status=0,width=648,height=395');
