I have been using a module from Business Tech to display my shops products in a Facebook app on my fan page. It app has been working fine right up to Prestashop 1.4.9
Since moving across to 1.5.3 the module no longer appears to work and I only get a server 500 error.
Does anyone else have the same module/problem. Do you know if it is related to a Facebook change or I am assuming more likely do to Prestashop 1.5.3... really hard to debug when you are unsure of the cause.
Any help would be appreciated.
