It looks like you have made the update correctly. The errors here are telling you that the open base dir directive is in effect. When this is set you can only include files that are within the specified path. In order to use include files you will either need to move all included files into the directory specified and update the paths or turn this restriction off. It would be much easier to turn this off. Depending on how it is set either directly in the ini or with safe mode being on you may need to contact your host to alter this setting.
