In the Recent log messages I get this message repeated many times:
Warning: array_flip(): Can only flip STRING and INTEGER values! i DrupalDefaultEntityController->cacheGet() (rad 388 av C:\wamp\www\includes\entity.inc).
I assume that the problem lies within one of the modules I have installed, but after spending the whole day trying to narrow down which module is causing the problem, without luck, I post this question. I have read other answers that relates to the same log message, but they did not help me.
Anyone that can explain how to get more info out of that warning?
