Hi all! I can't get to fix this searching thru this forum I found that for many people this solution Code: cd /root wget http://www.zlib.net/zlib-1.2.3.tar.gz tar xvfz zlib-1.2.3.tar.gz cd zlib-1.2.3 ./configure make test make install worked I tried it but still same error Code: tar: Error exit delayed from previous errors ./setup2: line 771: ispconfig_tmp/php/bin/php: No such file or directory ERROR: The PHP binary coming with ISPConfig does not work properly on your system! The installation routine stops here! [[email protected] maybe above solution works for CentOS, how about Fedora 4 ? any help is appreciated!
