PHP Warning: Invalid argument supplied for foreach()

Try re-saving the sesttings for the post type(s) in question to see if that triggers getting at least an empty array saved into the settings. Or fill in some labels and that should help as well.

No change..I’ve re-saved all the 3 post types, all three of them have the labels set. Same error..

Can you go to your tools menu inside the CPTUI menu and visit the “post types” tab. Curious what is in your settings at the moment that’s causing the error, especially if you have values saved.

Copy/Paste the content in the right hand side textarea, here into a reply.

Sure, here:

First

This is the info below “Settings”

Not quite what I was requesting, though close.

I wanted the info on the right hand side of this screen,

https://cloudup.com/cXlv7WnjNll which is what you should see when you click

which is what you should see when you click the “Tools” from this part:

https://cloudup.com/cpfgxDGqTRn

It’ll be a representation of your saved settings for the post types, and also allow me to import the same settings into my own installs, etc.

Ok, I see here is the data:

Not managing to recreate any warnings/errors with that output. Just on a whim, perhaps try importing that blob of code I had you provide, and see if that helps out at all. Just paste it into the left side and click the “import” button right below it.

Only other idea I have at the moment is possibly somehow duplicate options in the database, but it feels like a stretch.
