In the page of report of my drupal site, the upload progress module gives me an error. The error is the following:
"Upload progress Not trained
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."
I have tried to install the PECL uploadprogress library, but I have not succeeded there. There is someone who is able to point out whether to find the instructions for a correct installation of such bookstores. On my server Ubuntu 8.10 turns.
