Don't know if anyone is still following this but, try this fix:
I am not an expert in PHP, so perhaps if someone who is could check this. . . there may have been good reason the creator left it out. Basicly, use at your own risk.
Check your settings as mentioned above in the post. From your LyftenBloggie settings, under content, make sure intro text is turned off and read more is on.
Then find the file: components -> com_lyftenbloffie -> addons -> themes -> anemoi -> entries.php
Open up that file. Line 57ish find
<?php echo $entry->text; ?>
<div class="clear"></div>
immediately after that add:
<?php if($entry->readmore) : ?>
<p class="read-more"><a href="/<?php echo JRoute::_( 'index.php?view=entry'.$entry->archive.'&id='. $entry->slug ); ?>"><?php echo JText::_('READ MORE'); ?></a></p>
<?php endif; ?>
Save, upload the file back to where you found it. It is a good practice to rename the original file instead of replacing it, just in case something goes bad.
Find a longish blog entry, add a read more link at the top and save the blog entry. The link should be there now. You can adjust the style of the actual link by going to:
components -> com_lyftenbloffie -> addons -> themes -> anemoi -> CSS -> style.css
and find on line 59ish
#lyftenbloggie .blogcontent .read-more {float: right; margin-right: 10px}
and changing that line to: (add a "p" before ".read-more")
#lyftenbloggie .blogcontent p.read-more {... specify text size, color, ect. here ...}
there are a couple of other CSS modifiers on the lines immediately following this line. You can play with those if you want to do more stuff.
Again, save, upload to where you found the file.
Hope this helps. Cheers
