# HTTP 500 error after installing plugin

 * I have WordPress and BBPress installed, and I added the Cartpauj PM plugin [http://wordpress.org/plugins/cartpauj-pm/](http://wordpress.org/plugins/cartpauj-pm/)
   to have a private messaging system on the site. The plugin installed successfully,
   but I found an unwanted reply form on the botton of the private messages page
   on the website. So I deleted this from one of the PHP files of the plugin:
 *     ```
       //SHOW THE REPLY FORM
             $threadOut .= "</table>
             <p><strong>".__("Add Reply", "cartpaujpm").":</strong></p>
             <form name='message' action='".$this->actionURL."checkmessage' method='post'>".
             $this->get_form_buttons()."
             <textarea name='message_content'></textarea>
             <input type='hidden' name='message_to' value='".$this->convertToUser($to)."' />
             <input type='hidden' name='message_title' value='".$re.$message_title."' />
             <input type='hidden' name='message_from' value='".$user_ID."' />
             <input type='hidden' name='message_date' value='".current_time('mysql', $gmt = 1)."' />
             <input type='hidden' name='parent_id' value='".$pID."' />
             <input type='submit' onClick='this.disabled=true;this.form.submit();' value='".__("Send Message", "cartpaujpm")."' />
             </form>";
       ```

 * This is the PHP file that it was deleted from:
    [http://we.tl/45hrmdQ8uX](http://we.tl/45hrmdQ8uX)
 * Now the server reports HTTP 500 error for the whole website, even the admin dashboard
   is unaccessible at the subdirectory /wp-admin/.I found this odd, because this
   private messages plugin only adds a page and controls that, a separate page, 
   no embedded links on the site, yet now the whole site is gone, even the dashboard.
   How it is possible? Or maybe the site was hacked while I was managing it?

 * In the meantime, [FTP](http://codex.wordpress.org/FTP_Clients) into your site(
   or whatever file management application your host provides) & rename the wp-content/
   plugins/cartpauj-pm folder to wp-content/plugins/cartpauj-pm-old
