After upgrade from Prestashop 1.6.0.6 to 1.6.1.11 an error 500

Hello, I believe in client satisfaction and on time delivery . I have gained 7+ years of experience and profound knowledge in the field of web development . I can show you my all previous works done of several types in different different technologies. The price that i mentioned in bid is not fixed we can mutually decide it over chat. I am new to freelancer but it does not mean that I am new in this industry. I am hoping to have a positive reply from you. Regards, Manish
