Problem on installing rc, white screen

[thomas_g]

Hello,

I'm trying to install rc on my webserver (Ubuntu 14.04 Server, apache2) according to http://trac.roundcube.net/wiki/Howto_Install .

But the following problem occurs:
If I try to install rc 1.1.2 I get just a blank white screen when I call up "blablabla"/install.
If I try to install rc 1.1.1 the following message ist displayed: "Fatal error: Class 'PEAR' not found in "blablabla"/program/lib/Roundcube/bootstrap.php on line 102"

The php-pear package is - of course - installed.

Does anyone know what to do?

Thanks and best regards
Thomas

Are you using composer or are you manually downloading the Roundcube package?

[thomas_g]

I've manually downloaded the rc package

Are you downloading the Dependent or the Complete version?

[thomas_g]

I've been downloading the Dependent version, but I'm quite sure that I did what was suggested in the installation manual.
But now I tried the complete version. This worked just fine!

Thanks a lot!
