# Version: 4.0.40 causes HTTP 500 Internal Server Error

 * Have used this plug-in for several years on two sites on the same server. Some
   years back I had to change the permissions after updating on the Attachments 
   folder to 777 for it to work, but with recent updates this has not been necessary.
   Nevertheless, I always run a check after an update to see if any red warning 
   messages appear and do a test e-mail.
 * After updating one site today and trying to send an e-mail, I got warnings that
   the page was not available. I tried various browsers and all produced an HTTP
   500 Internal Server Error. All folder permissions were set to 755 and I tried
   changing the Attachments folder to 777 to no avail.
 * I proceeded to my other site and tried a test e-mail including an attachment 
   before updating and had no problem. After updating I now get the same HTTP 500
   error.

 * The line 976
 * `$img = new Securimage_ctf();`
 * in plugins/si-contact-form/includes/class-fscf-process.php should be
 * `$img = new Securimage_Captcha_ctf();`
 * since the class Securimage_ctf does not exist anymore in captcha/securimage.php,
   it is replaced with class Securimage_Captcha_ctf

 * Paljon kiitoksia! My plaudits for a quick effective response, which saved me 
   doing debugging.
 * The e-mails are now working normally on both sites.

 * Eipä kestä!
 * It took a while to search it this morning but solution is simple. I’m assuming
   a fix-update to pop up pretty soon 🙂
