Missing invoice button in FO for customers

[fotomaniak.cz]

Hi everyone,

 

I have Prestashop 1.3.2,

through the time it had quite some upgrades and code edits. After a while I decided to enable again download of PDF invoices for customers in their accounts. But even if I turned it on, any of my customers can see "PFD" button for download. I cant say if code was edited and I couldnt find any topic about it.

 

Can somebody please tell me where to restore it to default settings, or what files should I update to get it back up and running?

 

Invoice_screen_1 is clear instalation, with this button

Invoice_screen_2 is my store instalation, without this button, it should be in the border.

 

"Faktura" is translated "Invoice"

 

 

thanks for any help.
