Hello I have a few problems, the first is that the button Share events do not translate

Fix to 3.0.5:

Should be placed in \components\com_community\templates\default - events.viewevent.php - line 91

<li><a href="javascript:void(0);" onclick="joms.bookmarks.show('<?php echo CRoute::getExternalURL( 'index.php?option=com_community&view=events&task=viewevent&eventid=' . $event->id ); ?>')"><i class="js-icon-share"></i><?php echo JText::_('COM_COMMUNITY_SHARE')?></a></li>

Hello,

Thank you for pointing this out to us. I've already made sure our developer fix this problem! It should be available in next release.

I hope that helps.
