I am having the same problem as the guy here
http://wordpress.org/support/topic/117021?replies=2
except his seems to be resolved.
A four-digit hex number is displayed right before the header, before the footer, and on each file_get_contents call.
Any ideas?

This issue is caused by the so-called BOM (Byte Order Mark), which can be part of the UTF-8 signature.
Read more about this topic in the W3C FAQ about Unexpected characters or blank lines.
I removed the BOM using Dreamweaver by deselecting 'Include Unicode Signature (BOM)' under Page Properties > Title/Encoding. Read Dreamweaver Unicode normalizations and Byte Order Mark for more details about Dreamweaver and BOM.
