Following this I've instructed the system adminstrator to revert back the lib_xml to a previous version as it was updated to 2.11.1 and this is the cause of the issue, reverting back to lib_xml 2.10.3 fixed the issue. Althought this is just temporary as it will need to be updated to the latest version shortly, so I would suspect more users get into this issue by the servers updating to the latest version of lib_xml.
Please advise.
