I do have everything configured for the group "Default" to upgrade to the group "Member" after 2 hours of gameplay, yet still I, as a player in the group "Default" receive the message "... is in group Default and does not have a next rankup"

ranks:
    Default:
        requirements:
            time: 2h
#            votes: 11
        results:
            rank change: Default;Member
            command: 'say &p has been playing for two hours in total!;say &p has just become an Member and received 1000 Coins + Wooden Tools as a bonus!;money grant &p 1000;give &p 268 1;give &p 269 1;give &p 270 1;give &p 271 1;give &p 290 1'

It could be that your votes are not aligned correctly.

What do you mean?

Well, you can see the votes is not on the same line as the time requirement, so it will not count.

But I used # to deactivate that line

For the permissions plugin problem, I'm not sure. What perm plugin are you running?

GroupManager

Ah, sorry.

Could give the output of /ar debug?

Damnit! It is because the developer has changed the directory name from AutoRank to Autorank. This is so redundant when developers keep changing plugin and directory names. It constantly creates different dirs inside of the ../plugins dir, and consequently, raising inconvenience. Just would you guys stop changing dirs all the time? I mean, come on. Then, developers also keep changing configuration files names etc from, for example, config.yml to Config.yml. Why? Cannot you make up your mind? Oh man, I am sorry, but this is just so annoying.

This was changed over a year ago in the first beta. The 1.7 version you used was very old and dated from September 2012.

I changed it when the Autorank came into beta. So that was quite a long time ago.

I'm sorry that I changed it, but this was necessary to make sure there were no compatibility issues.

Roger that. Developers changing file names and folder names a lot in plugins, so the end-users always have this problem. It might be very useful if developers would announce that some filenames were changed. Maybe you did, but as you said, the change was made so long ago, it is hard to even remember now if you noticed that or not. Thank you for the support.
Well, this issue topic is useless, lol.

Good that it is fixed now ;)
