PascalVG Posted March 5, 2013 Share Posted March 5, 2013 Probably your server doesn't support this type of ciphering. You need an php extension mcrypt (ask your host about this). Until installed (or not possible) for now you can change it at Advanced preferences->preformance: ciphering. Choose "keep the custom blowfish class" Hope this helps Link to comment Share on other sites More sharing options...
kuldmedal Posted March 6, 2013 Author Share Posted March 6, 2013 I dont understand how cant it support it, when my site was working normally for many months and then the error came up. How can I change it when I cant get to my backoffice due to the error? Thank you for your answer Link to comment Share on other sites More sharing options...
tomerg3 Posted March 6, 2013 Share Posted March 6, 2013 Contact your host, and ask them to install it, they may have made changes / upgrades on your server. Link to comment Share on other sites More sharing options...
kuldmedal Posted March 6, 2013 Author Share Posted March 6, 2013 (edited) So there is no way to go around this? My host doesnt seem to be answering any of my letters.. And I need the site back up fast because orders are waiting shiping. Edited March 6, 2013 by kuldmedal (see edit history) Link to comment Share on other sites More sharing options...
tomerg3 Posted March 6, 2013 Share Posted March 6, 2013 You can turn it off directly from the database, ps_configuration table, though I don't recall the name of the top of my head. Link to comment Share on other sites More sharing options...
kuldmedal Posted March 6, 2013 Author Share Posted March 6, 2013 Could you please find it out, would be very grateful. I have no idea what to do in the ps_configuration table. Link to comment Share on other sites More sharing options...
tomerg3 Posted March 6, 2013 Share Posted March 6, 2013 Look for "PS_CIPHER_ALGORITHM" and change the value to 0 (it should be 1 now) 3 Link to comment Share on other sites More sharing options...
kuldmedal Posted March 6, 2013 Author Share Posted March 6, 2013 (edited) I cant seem to find this in ps_configuration? Edited March 6, 2013 by kuldmedal (see edit history) Link to comment Share on other sites More sharing options...

dahuegon Posted March 28, 2013 Share Posted March 28, 2013 Hi, I have the same problem, I have changed my hosting and my store has stopped working. I have done what I have read here and it works again but not at all. I can't go through categories, and some products work and other not. Any idea? Thanks.

Dh42 Posted March 28, 2013 Share Posted March 28, 2013 Hmm, your host might not support Prestashop. Do you have ajax cart enabled, if so does it work? Link to comment Share on other sites More sharing options...
Frank1957 Posted October 31, 2013 Share Posted October 31, 2013 Thanks for this post it fixed my problem going from Shared Hosting to VPS with GODADDY. Mcrypt is not installed on the VPS server. Link to comment Share on other sites More sharing options...
vekia Posted October 31, 2013 Share Posted October 31, 2013 if you've got VPS - it mean that you can configure own store, just use mcrypt library in php configuration Link to comment Share on other sites More sharing options...
cheeseplant Posted December 4, 2013 Share Posted December 4, 2013 Get this error when trying to enter my shop at www.korner.ee "Fatal error: Call to undefined function mcrypt_decrypt() in /home/korneree/public_html/classes/Rijndael.php on line 70" Whats the problem? I recently updated PHP 5.1to 5.3 and I got the exact same error because mcrypt needed reinstalling on server by host. All sorted within a few minutes. However, it took me a few hours to narrow it down to this issue - I made simple mistake and forgot to turn on debugging in my PS defines.inc.php which would have shown me the issue immediately. Big thanks to PS superstar El Patron http://www.prestashop.com/forums/user/295107-el-patron/ for his help. Link to comment Share on other sites More sharing options...
somits1 Posted November 2, 2015 Share Posted November 2, 2015 Hi, This is somit using prestashop v1.5.6 English version. and my website is http://www.slmobileprice.com I am trying to configure Performance - Ciphering option but getting error - The PHP "Mcrypt" extension is not activated on this server. Could you please tell me how to enable Rijndael with mcrypt lib. Mcrypt is faster than our custom BlowFish class, but requires the PHP extension "mcrypt". If you change this configuration, all cookies will be reset. Algorithm Use Rijndael with mcrypt lib. Keep the custom BlowFish class. Link to comment Share on other sites More sharing options...
Dh42 Posted November 2, 2015 Share Posted November 2, 2015 Contact your webhost they will have to compile it in with php on your server. Link to comment Share on other sites More sharing options...
