HTTP ERROR 500 on prestashop 1.6.1.13

[Gurnboy]

Hi All 

 

I hope someone can help me. I have 2 shops and both were working fine. I had been logged in and hadn't logged out but was working on something else for about a week, and when I went back to do some work on them I got the HTTP ERROR 500. I can't access the FO or the BO. Below is the error log but I don't know what to do next. 

 

Your help would be much appreciated.

 

Many thanks

 

Jamie

Ok so the code has been deprecated

 

return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $this->_key, $plaintext, MCRYPT_MODE_CBC, $this->_iv)).sprintf('%06d', $length);

 

Any ideas on what should replace it?

 

Or I can change the PHP version to 5.6, would this have any adverse effects to my site?

 

Many thanks

This is correct and it does not seem to be related to the PHP version you use. According to my information RIJNDAEL encryption doesn't work anymore.

Solved
