Yesterday I updated our site to EE 2.4.0 from EE 1.7.1. Today I noticed that I’m unable to update Field Settings for a custom field group under CP > Home > Administration > Channel Fields > Edit Field. When I click the Update button I get this error message:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Api_channel_fields::$config
Filename: libraries/Api.php
Line Number: 283
Fatal error: Call to a member function item() on a non-object in <full path removed for security reasons>/public_html/system/expressionengine/libraries/api/Api_channel_fields.php on line 1261
I don’t get this error when updating fields in the Default Field Group, however. Also I should note that we’ve renamed our system folder (not shown above for security reasons)
Any ideas?
