"Failed to use the skill due to an unknown reason."

I can't find a way to get rid of this

I think it started after I used one of those 20% boss dmg or def ignore potions at gollux. It was either then or when I went to Commerci trade union. I tried unequipping my decent skills, pets and pet equips but it didnt work. I don't have auto buff gem. I have restarted maple and my computer twice.

Please help if you have other possible solutions or any info about this glitch.

Use the potions again, but let them expire on their own.

I had this happen to me a few months ago, so I just used the potions, set up shop and went to sleep. The message went away after that.
