Cannot log back in: Parse error: syntax error, unexpected under function.php

Hi everyone,

I’ve having a freak issue on my website https://www.optimizestrength.com
As you can see, once you go to the site, I get the following error:

Parse error: syntax error, unexpected ‘<‘ in /home1/drginphd/public_html/wp-content/themes/Underfire/functions.php on line 233

I was trying to delete an [empty] tag that was appearing under my categories/archive and tried to add a code to solve it at the end of my function.php.

Something went terribly wrong after I deleted the line ( I added that code to the very end [line 233] ) and now the Parse error appears. I assume I must have deleted something important on accident.

Here is the full code of my function.php doc:
