Sub Blog is redirecting to Main Blog.

@iridionus – you were not quite clear exactly where you installed WP 3.0 and so looking from the outside into your site structure, I see WP 3.0 installed at https://www.professionalfilipino.com/wp3/ multisite – subdirectory structure. However, you seem to have a second WP install within because when I go to https://www.professionalfilipino.com/geodetic-blog/ I get the page to install wp-config.php file for another WP installation. Then you also have subdirectory folders with different SMF installations for each of the engineering fields.

I suggest some re-organization and cleaning need to be done within your site. Go to Super Admin > Blogs where it looks like only two sub-blogs have been created, Chemical Engineering and Civil Engineering. You would need to create the sub-blogs for the other engineering fields using the slugs you used in your HTML home page at https://www.professionalfilipino.com

@mercime

Thanks for the advice I’ll recreate them again.

Okay the problem still the same,
I hope someone will help me with this.

If you click the “Chemical Engineering Blog” the link stay.
but when you click the “Electronic Engineering Blog” the link redirect to the main blog.

Thanks in advance again.

Which URL did you enable the network for? If it’s for the one in the /wp3/ folder, the sites will *include* that in the URL.

Okay i got it.

You need to include the –> wwww
