I have long knocked my head because of this ...
I am trying to install the MyBB forum on my virtual server (CentOS 7, apache http server, php 5.4.3), and I ran into problems with file permissions. MyBB requires two files for writing, one of them is config.php, and the second is settings.php, both of them are in the directory inc.
I set the permissions for both files to 666. I wrote a simple test php page that mimics the way MyBB is tested for writeability:
<?php
echo('config: ');
$configwritable = @fopen('forum/inc/config.php', 'w');
if ($configwritable) {
echo('yes');
} else {
echo('no');
}
echo('<br/>');
echo('settings: ');
$configwritable = @fopen('forum/inc/settings.php', 'w');
if ($configwritable) {
echo('yes');
} else {
echo('no');
}
?>
Page exit
config: no
settings: yes
but if I list the files, they will be displayed as follows
root@localhost
-rw-rw-rw-. 1 krkavec krkavec 0 2. říj 22.49 forum/inc/config.php

BAM! , config .
