First letter cutting off in excerpt

I’m going to give you a hard-coded solution to this problem, rather than using a plugin. If you’re heart is set on a plugin that is fine – but this short code is rather simple and hopefully helpful for your purposes.

This code is basically just adding a CSS class to a shortcode.

First, deactivate that plugin.

Paste this in functions.php

// Shortcode: Drop cap
add_shortcode('dropcap', 'dropcap');
function dropcap($atts, $content = null) {
   extract(shortcode_atts(array('link' => '#'), $atts));
   return '<span class="dropcap">' . do_shortcode($content) . '</span>';
}

Use it like this:

[dropcap]K[/dropcap]

Then style it however you please in your stylesheet:

.dropcap { 
    font-size:50px;
}
