Hi, I made some tests yesterday and tried the submit approval functionality. Now I got warnings on every page of the CP.

A PHP Error was encountered
Severity: Warning
Message: Creating default object from empty value
Filename: models/publisher_approval_entry.php
Line Number: 90

A PHP Error was encountered
Severity: Notice
Message: Undefined property: stdClass::$channel_id
Filename: models/publisher_approval_entry.php
Line Number: 102

I also got this error when going to the Publisher module page

Entries
A PHP Error was encountered
Severity: Notice
Message: Undefined property: stdClass::$title
Filename: views/accessory-section.php
Line Number: 5

I just submitted an approval using an account with editor rights. Otherwise Publisher is working as expected, when I go and edit the entry, I got a popup saying that a draft is waiting approval. Thanks for your help. EDIT: I looked at that line 90

$row->data->member_data = ee()->publisher_helper->get_member_data($member_id);

And I tried to see if $member_id is defined correctly, and it is. A var_dump give me :

string(5) "22047"

About the line 102

$this->link_params['channel_id'] = $row->data->channel_id;

I dumped $row->data and I get
