I had the same problem with the 1.04 version of about-me-widget with 2.6 of WordPress. It appears that about-me has not been updated in approximately a year, and is no longer in synch with where TinyMCE files are named/located. I made it work by changing the code starting at line 36 as follows. This code replaces lines 36 to 73.
<?php $abdir= get_bloginfo( ‘siteurl’ ) . ‘/wp-content/plugins/’ . basename(dirname(__FILE__));
$extplugin = ‘advimage’ ;
$plugpath = $abdir . ‘/mce/’;
$getlocalcss = get_bloginfo(‘stylesheet_url’);
$admincss = $abdir . ‘/aboutmeadmin.css’; ?>
<script language=”javascript” type=”text/javascript” src=”../wp-includes/js/tinymce/tiny_mce.js”></script>
<script type=”text/javascript”>
tinyMCE.init({
mode : “textareas”,
theme : “advanced”
});
</script>
