I’m working on a 1.6.x site which uses the aforementioned extensions, and I’m running into the following problem: whenever I visit one of the draft/revision/preview URLs generated through Publish Plus, I get a series of these PHP errors:
A PHP Error was encountered
Severity: WarningMessage: preg_match() expects parameter 2 to be string, array given
Filename: extensions/ext.fieldframe.php
Line Number: 400
The page otherwise renders normally. We’re running the latest versions of both extensions (Publish Plus v1.1.1 and FieldFrame v1.4.2). Has anyone seen this problem or know how to fix it?
