i made the first ticket and since its been a full day no response im going to post it and hope its resolved

you can make most of the signs with only 1 perm
essentials.signs.color - this is needed to create the colored signs
other perms that are needed to abuse this bug is any of these

essentials.signs.use.buy
essentials.signs.use.free
essentials.signs.use.sell
essentials.signs.use.trade
essentials.signs.break.trade

Ok so to explain you would normally need the perm "essentials.signs.create.free" to make a free sign. if you do [free] on first line second line stone - with out the perm it will be black text and not work How ever if you do not have the create perm you can do
&1&1[free] - this by pass's the check for 1 color and makes the sign and works on trade signs buy signs sell signs allows you to spawn in any items and or money (you would need perms to use those signs or the perm to break if its a trade sign)

most of the use signs could be abused i listed the worst ones i could think of for me as a survival/eco server

if you disable the color signs in the essential config and if you have perms to color you can still color them even tho the #color is suppose to be disabled

how i temp fixed this was to just remove the perm for allowing users to color signs
