This is happing to most folders.
Third party plugins folder (plugins) [permissions failure]
Setup could not change the folder permissions from loose (0777) to strict (0755). You will have to set the permissions manually. See the Troubleshooting guide for details on Zenphoto permissions requirements.
Changed to 0755 Says attributes set. Then re run setup and this shows up
Third party plugins folder [plugins is not writeable and setup could not make it so]
Change the permissions on the Third party plugins folder to be writable by the server (chmod 777 plugins)
Looping cant move forward
