[Solved] Failed to set active templates Array#

After Installing Everything(Module, files... etc) i tryed to activate my template and i got an error "Failed to set active templates: Array ( [4] => )"

Does anyone has a clue of what i've may had done wrong?

bump!

It was permission issue giving the yams 744 permissions was not enough so just gave it full permission and is now working.

How did you give YAMS full permissions? Where? I'm having the same issue.

i think the yams folder in /assets/modules/yams or /plugins where ever it's located set to 777 or 755
