LGTM, not sure why the issue persists.
Have you checked that group and world have 'x' (directory search) permissions on every directory in the path to these files? (This is unlikely to be the problem but it's easy to check.)
And it shouldn't matter but those files themselves don't need 'x' (execute) permission.
Pretty sure the existence of the .bk file has nothing to do with this problem. Evidently you don't need it this time, but in the future you needn't hesitate to keep backups around if they would be useful.
