Fatal Error after Upgrade...please help

I just upgraded to 7.0.2 and now I have this error message on my index page.

This error message shows up and nothing else:

Fatal error: Call to undefined function bx_html_attribute() in /home/ustillup/public_html/inc/classes/BxDolTemplate.php on line 673

Any ideas??????

case 'page_keywords':
       if(!empty($GLOBALS[$this->_sPrefix . 'PageKeywords']) && is_array($GLOBALS[$this->_sPrefix . 'PageKeywords']))
     $sRet = '<meta name="keywords" c alt="' . bx_html_attribute(implode(',', $GLOBALS[$this->_sPrefix . 'PageKeywords'])) . '" />';
                break;
   case 'page_description':    
                if(!empty($GLOBALS[$this->_sPrefix . 'PageDescription']) && is_string($GLOBALS[$this->_sPrefix . 'PageDescription']))
                    $sRet = '<meta name="description" c alt="' . bx_html_attribute($GLOBALS[$this->_sPrefix . 'PageDescription']) . '" />';

Did you miss any files on the upload of the patch ?  Did you upload them in binary mode ?   Try to comment out the call to that function and see what happens......

Wow!  I really have no luck with these upgrades.

Everything on my site seems to work okay, except for the index page does not show up.  Instead I get that error.

Please see my site:

I've been playing around for almost an hour, but I really don't understand...

and sorry dolphin_jay - I don't know what you mean by comment out the call to that function

Okay, I uploaded all the files again from the upgrade package, and it now works.  I must have missed something.

Oh well, now to check it all out more closely and see how it's running.

PS. so dolphin_jay, you were right...I must have missed a file....  thanks.. ;-)

When I upgraded to D7.02 I had a database error. I then ran the upgrade, everything was ok after that.

When I upgrade I upload the individual files as opposed to uploading folders. I have not had any problems as such. The only problem I do have is the Forum _en language files will not update.
