Blogs can be on different domains if the different domains all point to the same directory on your server.

I don’t know about mapping different IP addresses, but I think if they’re all pointing to that same directory, it should work.

Is it possible to domain map the virtual blogs as well as assign specific IP:s to specific blogs?

Well, yes, the echo string is only for troubleshooting to see which page is the one that it stops/bugs at. The header error then tells me what is the next file in the chain. After that, I put the echo string in the next file to troubleshoot & so on.

However the “Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects. The webpage at http://wealthandsuccess.org/wp-admin/install.php has resulted in too many redirects.” error only occurs through the use of the VMB version of wp-config.php. When I replace it with the original wordpress wp-config.php file, my blog works fine (abeit not a multi-site blog). When I put the VMB file back, the error occurs again.

The only line I have changed in the wp-config.php is the following:
//define( ‘VMB_CONFIG_DIR’, ‘../../../config/’ ); //=>Not Working
//define( ‘VMB_CONFIG_DIR’, ‘/home/content/f/o/r/forcomcanada/html/config/’ ); //=>Works.
define( ‘VMB_CONFIG_DIR’, ‘config’ ); //=>Works.

Thanks.

As you may have guessed, the “headers already sent” error is caused by the “Hello filename” string you’re echoing. PHP throws that error if you try to set headers when something has already been sent to the browser — headers have to be first. So by the time pluggable.php tries to set headers you’ve already sent the “Hello” and it bugs out.

Beyond that I’m not sure what might be causing the redirect problem, other than something wrong with the config file.

UPDATE: line 897 in pluggable.php is a 302 header redirect part of the the function wp_redirect.php. I should also point out that the blog works fine when I use the original WordPress wp-config.php, but the above issue happens only when VMB is enabled with the VMB wp-config.php file. (wp-config.php File is in the root, but WP install is in /blog. I have added the correct path info as per your instructions). Thanks.

Hi Stephen,
I’ve instaleled VMB as per your instructions. The config folder is on the site root. Unfortunetly I’m getting an “Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.”
“The webpage at http://wealthandsuccess.org/wp-admin/install.php has resulted in too many redirects.”

By using an echo string (eg. “echo ‘Hello filename.php’;”) in each file along the way, I have traced that the code does work from index.php=>blog/wp-config.php=>mb-autoconfig.php=>mb-users.php=>html/config/mb-config-wealthandsuccess_org=>blog/wp-includes/pluggable.php. The trace stops there with “Warning: Cannot modify header information – headers already sent by (output started at /home/content/f/o/r/forcomcanada/html/blog/wp-includes/pluggable.php:1775) in /home/content/f/o/r/forcomcanada/html/blog/wp-includes/pluggable.php on line 897″

I have tried many options and nothing works. Do you have any insight on this that might be able to share with me so I can work this out? I’d appreciate it if you could help me. I’m going crazy and am at a complete loss now. Thanks.

Stephen, I did indeed set both variables, and when writing a new post it works as intended – the html code that gets expanded from the image upload looks correct.

The problem comes up when trying to view the post: As long as the setting of both WP_CONTENT_DIR and WP_CONTENT_URL are active, i.e. not commented out in my-config-wp2_local.php, accessing the url of the page returns only an empty page of 20B size, yet no html or anything visible inside.
When I comment out the setting of those variables in my-config-wp2_local.php, the post gets displayed as intended. Unfortunately there is no error displayed in the Apache error log.

Does this show any anomalities?
