Hello Friends..
erlier i also face same problem with master and content page and after doing lots of R&D i came up with some solution.
- Please check your web.config file. ( if you are trying to implement atlats in existing project then the configration of web.config file should be same when you create new atlas project)
- make sure that you ID of your content place holder in master page and contect in child page must not have a "_" charactor.. means ID="contect_Plaace1" is Invalid. id must be without "_"
- if you are using your own javascript in masterpage. then some time you are some time you are using dual conditional script then atlas not working..means for ex.
If (Screenwidth == 1024 && Screenheight == 769)
{
.................
}
if like above is there in your master page then atlas is not working bue
If (Screenwidth == 1024)
{
.................
}
and if script is like above then atlas is working...
Remove such script and then try to run atlats...
Hope this will helpful for you..
