My client is running Statamic v2.0.3 on Apache server with PHP 5.6.

When they try to upload an asset (usually a large PDF file) through the 'assets' fieldtype on a page in the CP, the Asset Manager window just spools indefinitely.

Here's the YAML for the field:

document: display: General Document instructions: fields: document_name: type: text display: Document Label instructions: null document_reference: type: assets display: Document Link instructions: null container: 380dc8d9-481c-4d18-9162-ecd5688f98a8 folder: documents max_files: 1

On the rare occasion that it loads the available assets, and one is selected, you get an error when trying to save the page.

Error log output: PHP Fatal error: Call to a member function disk() on null in /statamic/core/Http/Controllers/GlideController.php on line 39

Does anybody have any ideas what could be causing this?

Thanks in advance.
