Hello Anh,

Today after the update of MB I start getting this messages randomly in some fields (image_advanced) please check how it currently is: https://www.colorale.com/work/dji-com/

If I re-upload the images some are fixed but after I save I get the same error in the fixed one or in other fields.

Hi Ale, can you post the code you use on those locations?

Here’s the relevant part of the code.

the line with Warning: Invalid argument supplied for foreach() is the one with:

foreach ( $image_fields as $object_img ) {

Hi Ale, can you var_dump( $image_fields ) to see what values it has?

I re-uploaded one image and then that one and others start showing up, this is what I get with the images that are being displayed: array(1) { [0]=> string(4) "1227" }

I’ve tried to re upload all images and the message Warning: Invalid argument supplied for foreach() randomly shows in some images every time I update.

Can you send me a temporary admin account to check and fix that?
