Wrong Article displayed on Frontpage when logged in. - Joomla! Forum - community, help and support

hi,

i using front page blog layout home page of website , using joomla 1.5.15.

i want publish 1 article @ time , have used 'start publishing' , 'finish publishing' article options this.

i have set timings 1 article finishes publishing @ 23:59:59 , next article starts publishing 1 second later @ 00:00:00.

this works fine people viewing website guest, people log front-end registered or author. when log in, correct article appears on front page.

but when people log in front-end front-end editor, front-end publisher, manager, administrator or super administrator, wrong article appears on front page.

it displays article 'published expired' when 1 of these user groups log in front end of website.

i have experimented different settings, no avail!

the settings have are:

============================
menu

home page menu type - front page blog layout

parameters (basic)

# leading: 1
# intro: 0 ( don't use intro text, want display 1 article changes set dates)
columns : 1
# links: 0

parameters (advanced) :

category order - no, order primary order only
primary order - order

multi column order - across

pagination - hide
pagination results - hide
show feed link - no
=============================

mod_login

i have mod_login module set as:

login redirection page - home
logout redirection page - home

i have set them 'select item' front page loaded default.

=============================

i have created section called frontpage , category called frontpage , have timed articles in category!

but hasn't solved problem.

it's 'start , finish publishing' being ignored when user groups editing privileges log in front end.

perhaps i've got settings wrong?

hope can :-)

check time zone settings these users.
