I'll have a look, it's likely an issue with the newly added godmode integration, should be fixed in a jiffy.

Thanks for reporting, though.

Small question, could you share what plugins you dohave on the server? Perhaps there is one that conflicts with one of the optional dependencies.

Can't actually really reproduce the issue on my dev server, that's why I'm asking, anyways, 1.6.5 should fix it for you.

i have this too when i click on online Players

@tobse Could you share if you have a plugin called Godmode and share it's version please?
That bit of code should only execute when there is a plugin called Godmode available, I'll see if I can add more checks to be sure it's Godmode from this site (https://umod.org/plugins/godmode).

Perhaps someone made some other version that's not on uMod or not version v4.2.9 that's messing with the implementation... Would be real annoying if that's the case.

I'm still at work at the moment. I check it out as soon as I get home. I just saw through my root server app that I had godmode 4.2.8. I will install and test the latest version afterwards. then I'll get in touch. best regards

You seem to be missing a comma in your language file. Try adding it or removing the language file so it regenerates it.

Indeed, it lacked a comma in my Language F file.

Thank you very much, the problem has been solved. :)
