Parse error…

Hello – I did see there were some questions about this, but my problem is that I’m getting this error when trying to log in to my WordPress account:

Parse error: syntax error, unexpected ‘<‘ in /home/latour5/public_html/wp-content/themes/thesis_185/custom/custom_functions.php on line 105

I can’t get into my account to do anything to change it, nor do I know anything about fixing WordPress, as I had someone set this up for me, who’s not as available…

Can someone please help? I really need to get into my account… thank you so very much!
