Hi Cesaria,

Yes, the share-this plugin should not be updated unless you remove the call to it from the single.php template file. This is the only plugin that you are not recommended to upgrade, as it states in the README.txt file included with your theme package. The upgrade ads ad-ware and bloat.

If you want to use the newer version of share this, simply replace the <?php akst_share_link () ?> in the single.php file with the new share-this template tag, or remove entirely.
