if you are able to log into your back office, go to the performance page, scroll down to the Ciphering section, and choose the "use custom blowfish class" and see if that fixes the error.

If this solved your problem for now, so please take into consideration to do not upgrade your store. Prestashop has discarded blowfish a while ago. Now standard is rijndael class. I would better instead to use old deprecated cyphering method ask your provider to fix the problem on the server, for that you use rijndael.

On PS 1.7. you for ex. will not have the option to choose the class anymore.
