The map is not protected by default. It is likely that you have an addon that attaches something to the map which makes it protected. If it started lately, what did you install?

i believe it could be Zone Info 2 then ( https://www.curseforge.com/wow/addons/zoneinfo-2 ), i already posted the same log on there as well, i also came to the conclusion that it could be a "mixing" issue since it does add an info frame to the world map, and Mapster being used in conjunction ..... well we get this result :p

ty for your help, i have already seen you posted on my ticket for ZI 2 regarding this issue :)

I can confirm that ZoneInfo2 has indeed a secure button on its panel - even though it really doesn't need it. Secure Buttons are only useful if you want to cast spells or whatnot - it uses it to lock its panel in place. That causes the entire map to become protected due to the secure button, and all the taint errors show up.
