Reinstalling a custom module throws an error

[dargor]

Hello there,

I received an update from a custom module for prestashop 1.7.5, unistalled the previous version and tried to instal both, the new and the old version but I get this error shown in the images.

Anyone has faced this issue?

I think there is some place where the previous module info is getting cached.

I already deleted the content of /var/cache folder, deleted the module manually in the server in the /modules folder but the error persist. My user has superadmin rights, so I don't understand the message at all.

Thanks in advance.
