I installed the plug in on my website. When accessing xyz.com/events I get a 404 error, and xyz.com/category/events gives me the following code (blank page, this is the source code in the title, there is no <body> tag):
<b>Fatal error</b>: Call to undefined function thesis_output_title() in <b>/home/rachel/domains/survivingthestores.com/public_html/wp-content/themes/thesis_18/header.php</b> on line <b>16</b>
What does this mean? Do I need to reinstall the plug in or am I missing something somewhere? I'm confused as to how this plug in is supposed to work at all.
