Updating from Joomla 2.5.20 to 3.3.0

Prior to updating Joomla, I checked and found JFBconnect v 6.0.6 was compatible with 2.5 and 3. Therefore, I left it active.

After updating received this error
Fatal error: Class 'SCStringUtilities' not found in /home/iamhr1111/public_html/components/com_jfbconnect/libraries/widget.php on line 65

I went into my phpmyadmin and turned off all items for JFBConnect although the rest of the site functions.

I thought I would just reinstall JFBConnect which it does fine except when I go to autotune, it errors indicating it can't find component. I'm guessing that's because I have everything for it disabled. When I enable it errors.

I've looked over widget.php here is line 65 - 81...Any suggestions on what to look at?

Thanks,

Kevin

Edit: I realized that i had not uninstalled JFBConnect prior to re-installing. After I did I was able to install just fine. the majority of my settings were already populated.

As I have a couple other sites I'll be updating is there anything I should be aware of when upgrading? or is it best to uninstall and reinstall it?

$paramList = SCStringUtilities::replaceNBSPWithSpace($paramList);
$params = explode(' ', $paramList);

$count = count($params);
for ($i = 0; $i < $count; $i++)
{
$params[$i] = str_replace('"', '', $params[$i]);
if (strpos($params[$i], '=') === false && $i > 0)
{
$previousIndex = $this->findPreviousParameter($params, $i - 1);
//Combine this with previous entry and space
$combinedParamValue = $params[$previousIndex] . ' ' . $params[$i];
$params[$previousIndex] = $combinedParamValue;
unset($params[$i]);
}
}
return $params;

Thank you for your response. All is good, and I appreciate the feedback on completing the next upgrade.
