YUM encountered errors outside of EasyApache 4

I need help with Yum update. I get this on EasyApache page: YUM encountered errors outside of EasyApache 4. Log into the system via SSH to resolve them, or you can click the "Refresh" button to rebuild the system"s cache.
On Shell when I run um update I get this error:- [root@pcp2 ~]# yum update Loaded plugins: fastestmirror, rhnplugin, universal-hooks Traceback (most recent call last): File "/usr/bin/yum", line 29, in yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 375, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 170, in main base.getOptionsConfig(args) File "/usr/share/yum-cli/cli.py", line 263, in getOptionsConfig self.conf File "/usr/lib/python2.7/site-packages/yum/__init__.py", line 1079, in conf = property(fget=lambda self: self._getConfig(), File "/usr/lib/python2.7/site-packages/yum/__init__.py", line 420, in _getConfig self.plugins.run('init') File "/usr/lib/python2.7/site-packages/yum/plugins.py", line 188, in run func(conduitcls(self, self.base, conf, **kwargs)) File "/usr/share/yum-plugins/rhnplugin.py", line 138, in init_hook login_info = up2dateAuth.getLoginInfo(timeout=timeout) File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 232, in getLoginInfo login(timeout=timeout) File "/usr/share/rhn/up2date_client/up2dateAuth.py", line 200, in login li = server.up2date.login(systemId, socket.getfqdn()) File "/usr/share/rhn/up2date_client/rhnserver.py", line 63, in __call__ return rpcServer.doCall(method, *args, **kwargs) File "/usr/share/rhn/up2date_client/rpcServer.py", line 212, in doCall ret = method(*args, **kwargs) File "/usr/lib64/python2.7/xmlrpclib.py", line 1233, in __call__ return self.__send(self.__name, args) File "/usr/share/rhn/up2date_client/rpcServer.py", line 38, in _request1 ret = self._request(methodname, params) File "/usr/lib/python2.7/site-packages/rhn/rpclib.py", line 384, in _request self._handler, request, verbose=self._verbose) File "/usr/lib/python2.7/site-packages/rhn/transports.py", line 188, in request return self._process_response(fd, connection) File "/usr/lib/python2.7/site-packages/rhn/transports.py", line 216, in _process_respons e return self.parse_response(fd) File "/usr/lib/python2.7/site-packages/rhn/transports.py", line 236, in parse_response p.feed(response) File "/usr/lib64/python2.7/xmlrpclib.py", line 558, in feed self._parser.Parse(data, 0) xml.parsers.expat.ExpatError: syntax error: line 1, column 0
