I'm getting the following error a number of times on the Edit Entry page in the Control Panel after upgrading to Playa 4.4.4 on EE 2.5.5:
A PHP Error was encountered
Severity: Notice
Message: Array to string conversion
Filename: playa/helper.php
Line Number: 179
The front end seems to be ok.
PHP version is 5.2.17.
Fixed in 4.4.5, but passing along from P&T Support for 4.4.4:
Replace offending line in third_party/playa/helper.php with:
if (!is_array($category) && (strlen($category) > 4 && (strtolower(substr($category, 0, 4)) == 'not ') || (strtolower(substr($category, 0, 4)) == 'not_')))
