Looks like your onto something with the PHP not being able to support...
In /Environment when I update the component, there are two 'server checks' status 'check:'
1) php_extension intl Should be installed and enabled for best results
2) php_extension xmlrpc Should be installed and enabled for best results
lower on the same page under "Other Checks" there is an Error "check slasharguments error reading environment data (16)", same for each version of moodle that I need to upgrade to....
