Issue with Webmail and litespeed

[brainlag]

Hello all,

I have a quite intreasting configuration and a stupid issue !

I have a VPS with litespeed as webserver, and PHP Version 4.4.9 configured with the following options:

'./configure' '--prefix=/opt/lsws/lsphp4' '--with-litespeed' '--with-mysql' '--with-zlib' '--with-gd' '--enable-shmop' '--enable-track-vars' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-magic-quotes' '--enable-mbstring' '--with-gettext'

When i try to access horde webmail (i tried to install and re install with no luck) I get the following error:

Warning: main(Log.php) [function.main]: failed to open stream: No such file or directory in /usr/share/psa-horde/lib/Horde.php on line 3

Warning: main() [function.include]: Failed opening 'Log.php' for inclusion (include_path='/usr/share/psa-horde/lib:.:/opt/lsws/lsphp4/lib/php') in /usr/share/psa-horde/lib/Horde.php on line 3

Can you please help me ?

Thank you in advance for your valued (community) support
