1 hour ago, El Patron said:Modules use 'hooks'. It's possible that modules are 'not' hooked properly. I suggest, copying/saving any module configuration as you may need to reapply.
Then 'reset' the module, check and update module configuration as required.
Then check that module shows up as expected.
If not then you may need to uninstall, if you do this make sure you have module zip file backed up.
I have this module in 2 projects, one in 1.7.5 (new site) and it works well in frontend, but is not associated to payment category into the backend modules categories (thats strange). Then i have the same module in a site migrated from version 1.6 to 1.7, the same module in the last version that is working into the other prestashop site, but is not working here in the front end (and i have the same problem into the backend).
This is the module i'm using: https://github.com/mercadopago/cart-prestashop-7
