Thanks bro, I have received the zip password and it is currently working fine.
Regarding that post link, I spent half an hour searching at babiato but have been unable to find anything related to him, most likely related to corrupted forum data.
However, that incident struck me. It started when a member purchased the plugin and then shared it here, and that author posted and threatened that member, claiming to block the KEY of that sharer and claiming to already have his credit card information that could be used for retaliation. This shocked a lot of people and I'm sure those who read those contents have memories of this incident.
If I remember correctly, the original conversation that existed was at this link
https://babiato.tech/threads/request-redis-object-cache-pro-wordpress-plugin.27333/, but it has disappeared. If there are any members who remember this incident, they may want to come and add to it.
