I am presuming that the global $post is not returning.
For the short term i have suppressed errors on that line.
if(@$post->ID == $list->object_id)
Thanks & look forward to your response.
not sure if this will fix your problem but give it a go..
it worked for me!
here goes –
create a text file and name it ‘php.ini’
place this single line of code within the document and save it.
memory=20MB
this file needs to be placed in your live /wp-admin/ folder within your installation. Easy as that!
log in again and you should be good (fingers crossed!)
