Blender 2.8 Grease Pencil displays [Report ERROR: Nothing to erase or all layers locked] when trying to draw I got a graphic tablet and started trying out Grease Pencil, it was working fine, I was enjoying a lot, i switched from DRAW mode to Edit Mode, several times, suddenly while on Draw Mode there was a red dotted circle, I checked online and some people had that problem (they had Guides ON) this is not my problem, it displays REPORT ERROR: Nothing to erase or all layers locked - I have searched everywhere, can't seem to fix it, already downloaded version 2.81, same problem, the layers are not locked, the strange thing is that if I add a Grease Pencil Stroke, then the Red Dotted Circle is able to erase it, also the LINE, Arc and these other tools do work, but not the Draw Tool, which is what I actually need, please any help appreciated, thanks!
I had the same problem on my XPen Deco03.There is a button on my pen Pen/Eraser.
I accidentally pressed it and turned on the Eraser. Just toggle it back to Pen by one more click
