@kenzen I’d like to thank you so much for your explanation, I’ve just done that and it is working! Thank you @chouby. Have a nice day.
@kenzen Thank you so much for your help, I’ll try to do that! Thank you really so much and have a nice weekend
@chouby, thank you so much. Please, what should I do? should I uninstall my current version of Polylang and then reintall it by using that folder you linked before? Should I use the folder or only a specific file? Please let me know, because as I said I am not a developer and I am LOST! Thank you so much for your help.
