An ExpressionEngine install has begun to throw a "no access to the directory specified for this field" error when my client and I try to save updated entries.
The error relates to three optional image fieldtypes. If no image is selected for any of the three fields using File Manager I get the error. If I select an image for each field the error does not occur.
Our EE install is up to date: 2.5.3 and I've already checked that permissions on the upload directories are correct.
The Ellislabs support forums have a couple of instances of the same error (example here) but no solution.
Any help greatly appreciated.
I have just reproduced the error as a Super Admin and have a PHP error displayed on the Edit Entry screen:
A PHP Error was encountered Severity: Notice Message: Undefined index: filename Filename: libraries/File_field.php Line Number: 77
