Theme messed up Modules (PayPal, Credit Cards...)

[blazedani]

Hi,

 

After installing a free theme for Prestashop 1.6 I'm experiencing different problems.

 

Many modules are messed up.

PayPal: When a client pays with paypal the order is not created in the backoffice.

Credit Card: When paying with CC not order is created also.

 

It is very confusing... I don´t understand what is going on.
I reset, Unistalled & reinstalled the modules without any success.

I had to disable all this modules for now.

Anyone knows how can I solve this problem?

 

Thanks in advance!
