We are using Joomla1.5.20

Joomla Multisite Verion 1.2.8 - Free Version

Our URl Master Site URL is usentrepreneurtoday.com/

for which we have different slave sites like

newyork.usentrepreneurtoday.com/

pennsylvania.usentrepreneurtoday.com/

We are facing a strange issue.

The issue is that when we open our master site, the site is opening properly, but the different links in the master site takes to slave site links ( This is also not happening always mostly the links are pointed to master site and rarely it points to slave site and also the links is not pointed to the same slave site, this varies periodically, but at a time all the links are pointed to one wrong slave site

Kindly provide us a positive feedback which would enable us to overcome this error

First, we do not distribute or publish free version of JMS.

Second, you are trying to use a very old JMS version on a more recent Joomla version.
That 1.2.8 version was not qualified for this Joomla version and you have to use latest JMS version that you can buy at
www.jms2win.com/en/joomla-multisite?page...37&category_id=1

If you always see the master website, this is because the slave site domain is not correctly defined in JMS or that you didn't had a successfull save.
