no implicit conversion of String into Array - Rails 4.1.0.beta1 -

i have been dealing issue error: "no implicit conversion of string array".

to set in context: on rails 4.1.0.beta1, , using paperclip. trying add together watermark images. found next solution: watermark images paperclip, rails 4

i sort of got working @ point lastly night after receiving here stated error message - made slight change, had undone. , next error again?! might easy one, don't seem see it.

any help much appreciated.

here error message:

note if comment out watermark path of gallery & medium processors works fine. paperclip setup good.

--- other things noticed:

if remove contents of create - alter to:

def make

end

i still error. if can point me right direction awesome!

cheers.

to prepare , working had remove :processors => [:watermark] :gallery , :medium one.
