Hi,

We upgraded expressionengine to latest version and did a fresh install of Publisher addon.
Again same errors came up after installation:

A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: models/publisher_phrase.php
Line Number: 514

A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/site_name/public_html/system/codeigniter/system/core/Exceptions.php:170)
Filename: libraries/Functions.php
Line Number: 402

Also again, after install, upper menu in cpanel isn’t showing at all (disabling Zoo Flex Admin fixes this but its not a desirable solution).

This time, another problem occurs when Publisher is enabled. Front end of the site is showing errors instead of the actual site:

A PHP Error was encountered
Severity: Warning
Message: Missing argument 4 for Publisher_ext::matrix_data_query()
Filename: publisher/ext.publisher.php
Line Number: 759

A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /home/site_name/public_html/system/codeigniter/system/core/Exceptions.php:170)
Filename: core/Common.php
Line Number: 408

Fatal error: ob_start() [ref.outcontrol]: Cannot use output buffering in output buffering display handlers in /home/site_name/public_html/system/codeigniter/system/core/Exceptions.php on line 166

We did update P&T add-ons in the end.
Maybe the version of Matrix and Assets could be the problem?
Matrix - 2.2.2.1
Assets - 1.1.3
