If you encounter a Error 500 with the Flash uploader for NextGEN Gallery, it could be caused by the Mod_security addon for the Apache server. Thanks to the great response in the wordpress.org forums , there exists an easy work around for it. Add to your .htaccess file the follow exclude option :
<IfModule mod_security.c>
<Files upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>
Thanks to John Blackbourn for the hat tip !



Hello,
thanks for the post, but i´ve got another problem…
Error : Create Image failed. Check safe mode settings – if i want to upload an image. Any idea?
Thanks a lot.

i’m having the error 500 issue with wordpress 2.7.1… i tried modifying my .htaccess but nothing changes
Place the htaccess in the admin folder of the plugin, that should work
I have the error 500 even at activating the plugin. And I have to delete the plugin’s folder to get rid of it…
Any idea on that?
