Fatal error: Cannot redeclare Order::_getProductsDetail()

[Sergis]

Hola,

De repente, mi panel de backoffice esta fallando y dando este error . Por ejemplo cuando intento entrar en el apartado de configuracion

Alguien me puede ayudar a solucionarlo?

Did you perform an upgrade recently?  You appear to have a class override installed, which is no longer compatible with the core class.  This suggests that you performed an upgrade of Prestashop, or perhaps you installed a module that is not compatible with your version of Prestashop.

 

You will need to provide more information about what you have done.

I haven´t update neither presta nor modules.

 

I just recover a Data base copy, because i was having problems with default "transportation module" so i tried to go back to a previous copy to try to solve it.

 

Once recovered the troubkle started.

Still does not change the fact that you have a class override installed that is not compatible with your Prestashop version.  So either you always have had this issue, or you did something recently to create the issue.

 

You need to research why you have this override, it is likely a custom module you have installed, and then determine how to update the override so it works properly with your PS version

Thank you so much,

So can you help me to find it?  I'm new on that and I don´t know how to proceed

[bellini13]

You need to go through the modules you have installed and locate the one that included the override.  I do not have a tutorial on how to do that.
