Hello Tanvir,
Thank you for your replay.
Here is the description of what you claim to sell (and you are actually not, because it seems that this function is performed only if one payes more for an add-on):
https://retemodena.it/plugin-functionalities/
https://it.wordpress.org/plugins/download-manager/
(“control who can access to download”)
About the second problem: I would rather prefer to get rid of that button, the backup files are pretty big already and I would like to avoid single huge backup zip (or whatsoever) file. If you can, please let me know where could I make the modifications to achieve it so. Otherwise, I will give you admin access as soon as I get back from my trip (next monday).
Thanks
