Well, since you don't appear to be online, I'll leave some instructions here for you.
I am assuming that your primary domain name (which will also be your public_html folder) is
www.thai-land-house.com. I will assume this to be the case. If your directory that you are publishing to is something different, then you will need to change it accordingly.
yes, thai-land-house.com is the primary domain name
1. Bring up your underconstruction page in bluevoda. Go to file, save page as and type index . Nothing else before or after it. Just index . Save it. Assuming your other index page you created is in the same directory, then it will come up and say something like. ......index already exists, Do you want to replace it? You will say yes. When you do that, your underconstruction page will become your index page. If you had anything on the index page, it will be gone. (So if you want to save the old index file first, save it as something else, so that you have it, before you write over it.)
I was too late for this so I've lost the original index page.
Ok, now you should have your (old underconstruction page) as your index.bvp page. save and publish that page to your public_html/thai-land-house directory (again assuming that is the name of your site directory. If not replace the thai-land-house with whatever the name of the directory you are using is.
After re-nameing the 'underconstruction' page to 'index' i just clicked 'publish' assuming this was the right thing to do. When I type in www.thai-land-house.com the page still comes up 'underconstruction'..
After you publish it, then you should be able to type in
www.thai-land-house.com in your browsers url and bring up your (old underconstruction page).
To answer your other question, to delete your old underconstruction page.....with your bluevoda program up, go to Tools, FTP Manager, click on connect, enter your user name and password (the same one you use to access your cpanel). That will connect you to your FTP manager. On the left side you will see your files that are stored on your harddrive. On the right side are the directorys and files stored on the web server. Find the directory and "underconstruction" page on the right side, select it and delete it. That simple. Disconnect and your done.
I'm into the FTP manager and can not find 'underconstruction'....
I hope this helps and good luck to you.
