[Plugin: Ultimate Post Type Manager] Invalid argument supplied for foreach() in

I’m seeing this too,
however after I applied your fix, I am now unable to access the plugin page.

Is there any other fix I can apply?

you probably done something wrong since it has no effect on the plugin page.

anyway i posted the other solution above:

or you can check the count of $cpts before calling the foreach and if its 0 then skip it.

Tried it again, blank page.

Here’s a screenshot. https://twitpic.com/7zbggc

from that screenshot it looks like you are missing an opening { at the end of that line it should say:

foreach((array)$cpts as $cpt){

Thanks man.
