[imp] Blank Screen after login

[Will]

Hi all,

I am new to imp and horde so i opted to install the RPMS on the horde site,
hence i have installed

apache-1.3.27-1.7.2.i386.rpm from RedHat

curl-7.9.5-2.i386.rpm
mcal-0.7-0horde2.i386.rpm
curl-devel-7.9.5-2.i386.rpm
mcal-devel-0.7-0horde2.i386.rpm
db3x-3.2.9-4.i386.rpm
php-4.2.2-0horde3.i386.rpm
php-devel-4.2.2-0horde3.i386.rpm
php-imap-4.2.2-0horde3.i386.rpm
js-1.5rc4-2.i386.rpm
php-mcrypt-4.2.2-0horde3.i386.rpm
js-devel-1.5rc4-2.i386.rpm
php-mysql-4.2.2-0horde3.i386.rpm
libmcrypt-2.5.6-0horde2.i386.rpm
php-snmp-4.2.2-0horde3.i386.rpm
libmcrypt-devel-2.5.6-0horde2.i386.rpm

sablotron-devel-0.82-1.i386.rpm
libxml2-devel-2.4.19-4.i386.rpm
libxml2-python-2.4.19-4.i386.rpm
ALL FROM HORDE SITE

and

horde-2.2.3-1.noarch.rpm
imp-3.2.1-1.noarch.rpm
ALL FROM HORDE SITE

I have built and am running IMAP 2001a successfully

All the database tables etc have been created and the config files have been
altered for imp login etc

Now the problem at hand is that after i log in to imp using imap proto on
localhost with correct username and password the next screen comes up blank.
The url shows that data has been posted and apache logs show the post
request but it is still blank.

Any help would be much appreciated.

Thanks

Will
