I've been looking for a week for an answer to this, but maybe someone can point me to the right place. I can't be the only person to have had this problem. I suspect it's a server problem, and there are two issues
1) Before I can set up permalinks I have to edit wp-admin/includes/misc.php
2) When setting up multisite, after editing wp-config.php, the network setup screen is blank. I found a fix which requires some core hacking (again) http://wordpress.org/support/topic/networkphp-is-blank-cant-create-a-network?replies=26
From my phpinfo -
Configure Command './configure' '--disable-fileinfo' '--enable-bcmath' '--enable-calendar' '--enable-exif' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-mbstring' '--enable-pdo=shared' '--enable-sockets' '--prefix=/usr' '--with-curl=/opt/curlssl/' '--with-curlwrappers' '--with-freetype-dir=/usr' '--with-gd' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mysql=/usr' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--with-mysqli=/usr/bin/mysql_config' '--with-pcre-regex=/opt/pcre' '--with-pdo-mysql=shared' '--with-pdo-sqlite=shared' '--with-pic' '--with-png-dir=/usr' '--with-sqlite=shared' '--with-xpm-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr'
I don't have to do either of these "fixes" on another server, but I want to use my own VPS and I can't work out what is different. Can anyone point me in the right direction?
