Thread:Project:Support desk/Blanc Page after MediaWiki Update 1.23.5 to 1.24

I have an Ubuntu Server with MySQL and Apache.

I've first updated my wiki from 1.23alpha to 1.23.5. Everything was fine.

Then I've updated from 1.23.5 to 1.24 and I get blanc pages. Everything is blanc. Source code of the Website is also empty.

My error log shows:

PHP Warning: require(/var/www/includes/WebStart.php): failed to open stream: No such file or directory in /var/www/mywikifolder/index.php on line 36

and

PHP Fatal error: require: Failed opening required '/var/www/includes/WebStart.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/mywikifolder/index.php on line 36

I've applied chmod 755 to WebStart.php with no change

After that also chmod 755 -R to includes folder with no change

What do I have to do?

What does this mean:

(include_path='.:/usr/share/php:/usr/share/pear')
