schnap

The last one worked! genius! 😉

Edited .htaccess file – nothing happens either

The folder is named just “media-grid”.
I’m not that advanced to make use of the code you gave me(shame on me). I’d be grateful if you lead me where do I exactly put that code :p I’m a newbe

If its not enough, I can give ftp access via mail – just give me ur mail

I’d try to provide you the code u need

Lets start with share icons in lightbox:

// SOCIALS
			if(get_option('mg_facebook') || get_option('mg_twitter') || get_option('mg_pinterest')) :
			  $dl_part = (get_option('mg_disable_dl')) ? '' : '#!mg_ld_'.$post_id;
			  if(isset($pc_post_id)) {$post_id = $pc_post_id;}
			?>
              <div id="mg_socials" class="mgls_<?php echo get_option('mg_lb_socials_style', 'squared') ?>">
            	<ul>
                  <?php if(get_option('mg_facebook')): ?>
                  <li id="mg_fb_share">
					<a onClick="window.open('https://www.facebook.com/dialog/feed?app_id=425190344259188&display=popup&name=<?php echo urlencode(get_the_title($post_id)); ?>&description=<?php echo urlencode(substr(strip_tags(strip_shortcodes(get_post_field('post_content', $post_id))), 0, 1000)); ?>&nbsp;&picture=<?php echo urlencode($fi_src[0]); ?>&link=<?php echo urlencode(lcwp_curr_url().$dl_part); ?>&redirect_uri=http://www.lcweb.it/lcis_redirect.php','sharer','toolbar=0,status=0,width=548,height=325');" href="javascript: void(0)"><span title="<?php _e('Share it!', 'mg_ml') ?>"></span></a>
                  </li>
                  <?php endif; ?>

                  <?php if(get_option('mg_twitter')): ?>
                  <li id="mg_tw_share">
					<a onClick="window.open('https://twitter.com/share?text=<?php echo urlencode('Check out "'.get_the_title($post_id).'" on '.get_bloginfo('name')); ?>&url=<?php echo urlencode(lcwp_curr_url().$dl_part); ?>','sharer','toolbar=0,status=0,width=548,height=325');" href="javascript: void(0)"><span title="<?php _e('Tweet it!', 'mg_ml') ?>"></span></a>
                  </li>
                  <?php endif; ?>

                  <?php if(get_option('mg_pinterest')): ?>
                  <li id="mg_pn_share">
                  	<a onClick="window.open('http://pinterest.com/pin/create/button/?url=<?php echo urlencode(lcwp_curr_url().$dl_part); ?>&media=<?php echo urlencode($fi_src_pt[0]); ?>&description=<?php echo urlencode(get_the_title($post_id)); ?>','sharer','toolbar=0,status=0,width=680,height=470');" href="javascript: void(0)"><span title="<?php _e('Pin it!', 'mg_ml') ?>"></span></a>
                  </li>
                  <?php endif; ?>

                  <?php if(get_option('mg_googleplus') && !get_option('mg_disable_dl')): ?>
                  <li id="mg_gp_share">
                  	<a onClick="window.open('https://plus.google.com/share?url=<?php echo urlencode(lcwp_curr_url().$dl_part); ?>','sharer','toolbar=0,status=0,width=490,height=360');" href="javascript: void(0)"><span title="<?php _e('Share it!', 'mg_ml') ?>"></span></a>
                  </li>
                  <?php endif; ?>
                </ul>

              </div>
            <?php endif; ?>

Seems like these are font-awesome generated icons in “Media grid” plugin.

check the sites I linked in first post, then click on image gallery on each and see what’s missing
