Topic: Use chmod in install.php
I was looking at this
// Check if the cache directory is writable
if (!@is_writable('./cache/'))
$alerts .= '<p style="font-size: 1.1em"><span style="color: #C03000"><strong>The cache directory is currently not writable!</strong></span> In order for PunBB to function properly, the directory named <em>cache</em> must be writable by PHP. Use chmod to set the appropriate directory permissions. If in doubt, chmod to 0777.</p>';
// Check if default avatar directory is writable
if (!@is_writable('./img/avatars/'))
$alerts .= '<p style="font-size: 1.1em"><span style="color: #C03000"><strong>The avatar directory is currently not writable!</strong></span> If you want users to be able to upload their own avatar images you must see to it that the directory named <em>img/avatars</em> is writable by PHP. You can later choose to save avatar images in a different directory (see Admin/Options). Use chmod to set the appropriate directory permissions. If in doubt, chmod to 0777.</p>';I'm not sure if it makes sense, but I think the code should look more like this (replace 0777 with the appropriate number, I haven't used chmod before 
)
// Lets try using chmod, just in case
@chmod('./cache/', 0777);
@chmod('./img/avatars/', 0777);
// Check if the cache directory is writable
if (!@is_writable('./cache/'))
$alerts .= '<p style="font-size: 1.1em"><span style="color: #C03000"><strong>The cache directory is currently not writable!</strong></span> In order for PunBB to function properly, the directory named <em>cache</em> must be writable by PHP.
