Question

I have problem on my blog: http://osify.com while processing add new post with above error message. I tried to disable all plugins or changed theme, the error is still the same.
I found the issue might link to the media upload, it is not be able to post any image, it’s waiting at: “Crunching…” with no continue but the file was in the folder (checked via FTP)

And I already tried to chmod the folder to 777 (before it’s 755 for folder, 644 for files)

I think it might link to multi-site issue on shared hosting but no clear idea or clue about that.

My .htaccess

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]


<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
[..]
# BEGIN WordPress
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress

It seems just happen when I enable my sub site
Is there any way to solve this issue?

Thanks for advise,

The amount your .htaccess is ganked….

REMOVE this part up at the top.

    #uploaded files
    RewriteRule ^(.*/)?files/$ index.php [L]
    RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
    RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2 [L]

    # add a trailing slash to /wp-admin
    RewriteCond %{REQUEST_URI} ^.*/wp-admin$
    RewriteRule ^(.+)$ $1/ [R=301,L]

The ONLY WP calls you should have in there should match this: http://codex.wordpress.org/Multisite_Network_Administration#.htaccess_and_Mod_Rewrite
