Backward Compatibility Issue

[tombruty]

Hi,

 

I have tried to upgrade the PayPal module from version 2.8.5 to 3.4.9 on Prestashop version 1.4.2.5. After installing the module I was advised that in order for the module to work correctly I needed to install the backward compatibility module (version 0.4.5). After doing this the module page would not load and I get the following PHP error:

 

Cannot redeclare class BackwardCompatibility in /Sites/xxxxx.com/source/trunk/modules/backwardcompatibility/backwardcompatibility.php on line 162

 

I was trying to upgrade the module to fix and issue related to PayPal error 10415. My client recevied an email from the module advising them that there was a transaction error however the customer was charged and the order is in the database but not visible in the admin. After reading various posts in forums I concluded that I needed to upgrade the module. Here is one example:

I would really be grateful of any help or advice that would enable me to upgrade the module.

 

Thanks in advnace.

Hi Phil,

 

It turns out the issue I was trying to fix didn't require a module upgrade so I never ended up having to resolve this problem. I did however eventually get a response from Prestashop support:

 

You need to delete the paypal module from your host and first install backward compatibility and then the new version of paypal.

 

I hope it works for you.

thank you "tombruty"  that's the good answer !

> delete paypal from the host

> delete the backward compatibility module from the backoffice

> re-install the backward compatibility module

> re-install the paypal module

 

and that's it !!!
