Redmine

When I remove the attached file redmine gives error 500, but the file that is removed, as seen when reloading the page with the attachment again. What could be wrong?

cat ./.htaccess

1. General Apache options
   #<IfModule mod_fastcgi.c>
2. AddHandler fastcgi-script .fcgi
   #</IfModule>
   #<IfModule mod_fcgid.c>
3. AddHandler fcgid-script .fcgi
   #</IfModule>
   <IfModule mod_cgi.c>
   AddHandler cgi-script .cgi
   </IfModule>
   Options +FollowSymLinks +ExecCGI

1. If you don't want Rails to look in certain directories,
2. use the following rewrite rules so that Apache won't rewrite certain requests #
3. Example:
4. RewriteCond %{REQUEST_URI} ^/notrails.*
5. RewriteRule .* - [L]

1. Redirect all requests not available on the filesystem to Rails
2. By default the cgi dispatcher is used which is very slow #
3. For better performance replace the dispatcher with the fastcgi one #
4. Example:
5. RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
   RewriteEngine On

1. If your Rails application is accessed via an Alias directive,
2. then you MUST also set the RewriteBase in this htaccess file. #
3. Example:
4. Alias /myrailsapp /path/to/myrailsapp/public
5. RewriteBase /myrailsapp

RewriteRule ^{$ index.html [QSA]
RewriteRule ^([}.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
#<IfModule mod_fastcgi.c>

1. RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
   #</IfModule>
   #<IfModule mod_fcgid.c>
2. RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
   #</IfModule>
   <IfModule mod_cgi.c>
   RewriteRule ^(.*)$ dispatch.cgi [QSA,L]
   </IfModule>

1. In case Rails experiences terminal errors
2. Instead of displaying this message you can supply a file here which will be rendered instead #
3. Example:
4. ErrorDocument 500 /500.html
