Dear all;

How are you?

I am a new on Drupal.

Recently, I got the final version of our project website from the commercial company and I created a development version of my Drupal, which is the exact same copy of the production server.  I got the following errors when I accessed “wiki” and “blog”s. My wiki is made with “Book” module.

Fatal error: require_once() [function.require]: Failed opening required 'Text/Wiki/Mediawiki.php' (include_path=':.:/usr/lib/php:/usr/local/lib/php') in /usr/lib/php/Text/Wiki.php on line 473

You can check it out in my server : http://lnkd.info/wiki/agrodep-wiki

I tried to fix it.
I found that the file “Wiki.php” in  the /usr/lib/php/Text/ folder. But, I don’t know how to fix it. My guess is that I need to fix it in the Drupal instead of   PHP file.

Is there anyone who knows some clue or hint to fix this problem?

Do I re-install new version of modules?

Thanks for your help in advance. : )

Best Regards,

Soonho
