ref password problem

I can't find any solution so I ask here. I stupidly typed in my config "seta ref xxx". Since that moment I can't ref log in on the server. The command "/ref" is treated just like other r_, cl_, cg_ etc commands. When I write it in the console it's like: "ref is xxx; default: xxx"

I of course deleted that line from my config, deleted it from etconfig and from the config which was in my etpro profile. Do you have an idea how to clear that out from my et?
