Please add support for +

In this case a placeholder ends with +, meaning we insert a space " " automatically if it's not empty

Placeholders, in general, shouldn't contain any characters other than alphanumerical ones (a-z and 0-9) as for issues like you experience right now.
You should report this to the dev of the plugin too, as it is against any common way of making placeholders in a plugin work.

@Andre601 placeholders hasn't anything todo with permissions. Second placeholders with a + is normal just take a look at placeholderAPI Wiki

Just fyi: I made the wiki so I know it all too well, and if you look closely will you notice that none of the displayed placeholders contains a + (Ctrl + F, then search for "+" and the only thing you'll find is the names of the plugins)

Sounds like this is something that your placeholder plugin could provide. :)

I imagine it would also be quite easily done using PlaceholderAPI's JS expansion (https://github.com/PlaceholderAPI/Javascript-Expansion/wiki) - although you didn't specify which placeholder plugin you were using!
