I tried to install a new theme for my site. When I try to access my site, I get the following error:

Fatal error: Call to undefined function networkbar() in /home/hokiepo1/x_data/caches/smarty_compile/http%253A%252F%252Fhokiepoker.com%25%25wordpress-subbliss-default^%%62^621^621B4937%%theme.html.php on line 53

Now I can't get back to my site to undo the error. Anyone out there who can help?

Which theme do you want to install, and how did you install it? In which folder?

I installed subbliss from sublimedesign.org. Here is the readme:

/////Intro/////

I unzipped the folder structure for subbliss to the /public_html/themes folder. I went to my admin panel and selected the theme form my list.

Did you try: /index.php?xoops_theme_select=default ?

2 things I don't understand:
theme.html.php ? Normally a theme only has a theme.html, not a theme.html.php. Try renaming that file to theme.html

wordpress-subbliss-default is the other thing I don't understand.

Any clue why this shows up? It's kinda weird to get this..
