I've run into a bit of a dead end on something. I have two servers, one development (Mac) and the other production (Linux), both running Silverstripe on Apache. On Linux, Firefox returns an XML Parsing Error on a number of my pages, but cannot specify where the error is.
It will say the error is located at Line 1, Column 1 and the error is: 208f (or some other hex value). I've attempted to remove the <?xml> header at the beginning of the Page.ss, however Firefox will still return the characters to the top of the screen as if it was part of the output.
I'm having the same problem, only with the admin logon form.
2148 is being prepended before the start of the document, and 0 is appended after the closing </html> tag.
Has anyone figured out exactly what causes this? It's certainly only cropped up over the last day which means some tiny little layout change I made (without testing?!), or my users that have started adding content recently.
