Errors reported by Codestyling Localization

Hi, I am using the Codestyling Localization plugin http://ww.wp.xz.cn/plugins/codestyling-localization/ and it is reporting some errors. Do these need to be fixed? (They do not seem to be preventing the software from running.)

PHP runtime error reporting detected !
Reason: some executed PHP code is not written proper | Originator: unknown (probably by Theme or Plugin)
Below listed error reports has been traced and removed during page creation:
