I've got that script that e-mails errors to me installed on a SS 2.4.0 customer website. Periodically I'm getting flooded with the same error and I can't get rid of it.
Error at sapphire/core/Object.php line 724 (http://bizbuild.co.uk/admin/EditForm/field/Events/item/29/assets/Uploads/OSWnew.jpg)
Error: Uncaught Exception: Object->__call(): the method 'assets' does not exist on 'DataObjectManager_ItemRequest'
At line 724 in /hsphere/local/home/bizbuild/bizbuild.co.uk/sapphire/core/Object.php
I've tried my best to deduce the cause, to me it looks like MCE editor is including an image from the SS assets/Uploads folder and is somehow requesting an invalid URL along the way? The MCE editor is set up on the description field for items within a DataObjectManager.
Please help o' cheesey one.
