Upgrading Drupal

I did updates a few days ago to some modules, I'm not sure if this has anything to do with that, but when looking trying to look through "recent log entries" under Administer, a huge red box appears with these warnings. Can anyone help me to figure out what is the issue and how I can resolve it please?

warning: Invalid argument supplied for foreach() in /home/xxx/includes/common.inc on line 789.
warning: strtr() [function.strtr]: The second argument is not an array in /home/xxx/public_html/includes/common.inc on line 806.
warning: Invalid argument supplied for foreach() in /home/xxx/public_html/includes/common.inc on line 789.

Next, when looking at the status report after updating those modules to see if everything installed correctly, there was a yellow box with this message

"Upload progress Not enabled
Your server is capable of displaying file upload progress, but does not have the required libraries. It is recommended to install the PECL uploadprogress library (prefered) or to install APC. "

This is the clickable link website that is listed next to "(prefered)" http://pecl.php.net/package/uploadprogress.

hi guys,

im new to drupal (i have 5+ years of joomla development but trying to grasp drupal at the moment)

ive been asked to upgrade a drupal installation from 4.7 to 6.10 (and make some enhancements)

can someone tell me is there a clean migration path (script even?) from 4.7 to 6.10 or does it get messy ?

thanks for info
Chico

I converted an 5.1 module to 6.10 by the deadwood project... and I have some errors:
What is wrong in this line?
$items['modul/Dodaj','title' => ''] = array('page callback' => modul_Dodaj, 'access arguments' => $access);
The error I have is Parse error: syntax error, unexpected ',', expecting ']' in /drupal-6.10/modules/iBA_PF/iBA_PF.module on line 27

Are there any issues I need to be aware of in upgrading from Drupal 5 to Drupal 6?

Thanks.
