[imp] Webmail Error

[Peter Nyamukusa]

Hi Guys,

I am new to Horde and yesterday I tried to upgrade my php in order to run
another application then I got an error on my webmail as below all my other
websites are running fine


Warning: main(PEAR.php): failed to open stream: No such file or directory in
/var/www/test.com/horde/lib/Registry.php on line 13

Fatal error: main(): Failed opening required 'PEAR.php' (include_path='.:')
in /var/www/test.com/horde/lib/Registry.php on line 13


Any pointers would be appreciated

Cheers 
Peter
