I'm also having a similar problem with error:
Warning: main(include/rcube_shared.inc): failed to open stream: No such file or directory in /home/bpcurt2/public_html/roundcubemail/index.php on line 79
Fatal error: main(): Failed opening required 'include/rcube_shared.inc' (include_path='/home/bpcurt2/public_html/roundcubemail/:/home/bpcurt2/public_html/roundcubemail/program:/home/bpcurt2/public_html/roundcubemail/program/lib:.:/usr/lib/php:/usr/local/lib/php') in /home/bpcurt2/public_html/roundcubemail/index.php on line 79
I've checked and the permissions are 777.
One thing I didn't understand is in the Install instructions here:
http://trac.roundcube.net/trac.cgi/wiki/Howto_InstallIt says things like "The two files are in the "/config/" directory of Roundcube" and "Next we execute the SQL file found in the "/SQL/" directory in Roundcube" but the roundcube files I downloaded here:
http://prdownloads.sourceforge.net/roundcubemail/roundcubemail-0.1beta2.tar.gz?downloadare all in one single directory with no sub-directories...
Thanks in advance for any help you can give...
