argumenterror: provided regular expression using multiline anchors (^ or $), may present security risk. did mean use \a , \z, or forgot add :multiline => true option? this error occurs when trying upgrade previous version of rails rails 4.0.0.
regexp validation validates_format_of.
if don’t expect multiline incoming data, need replace “^” “\a” , “$” “\z”. if expect multiline strings, specify multiline: true option.
not sure of specific reason error, try updating devise latest version supports rails 4.0.0.
