Livesite preview issue

dipti

Did some changes in
file ui-common.xml at location
[iw-home\httpd\webapps\content_center\WEB-INF\conf\livesite]

to enable the "Generate ASP" command."

Save the file and copy it to the location

[iw-home\local\config\lib\content_center\customer_src\ etc\conf\customer]

Build the tool-kit.(build.bat)
We then got the option of Generate Asp but when we tried to preview the component it showed blank as in the image added

Then we reverted the changes and then again executed the build.bat file showed the same
So finally we executed the build.bat install file

Not allowing to preview new components and existing components
