I did the same thing you said, but the issue still occcurs. If you want detailed info, I renamed/deleted the file in the following path: addons/amxmods/data/vault/CRXRanks.vault I also tried to download the latest version of the Rank System, I already had the latest but I just wanted to try if something changed. Yet the error still occurs. Here's a picture if you wondered, and I'm using FTP.
