Hi Brian

I have a Blueprint install on an ExpressionEngine site and am getting the following error message when switching between layouts:

A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: playa/ft.playa.php
Line Number: 1532
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /Users/tinyv/Sites/iStrategy/system/codeigniter/system/core/Exceptions.php:170)
Filename: core/Common.php
Line Number: 412

I am using Playa (a single selection drop-down from specified range of channels) within three Matrix fields for this channel.

Also, not sure if it is related but getting same problem as reported at http://boldminded.com/support/ticket/141 with trying to update Publish Layout thumbnails. Tried reinstalling themes folder but not working.

For reference am using a custom themes location (if site root is at /public/ themes are located in /public/libs/themes/) and also using the Assets add-on for file management.

The site is local at present so not able to provide an EE install - once have in a live environment can update ticket with details or supply these via email.

Regards,

Cole
