Multisite wp-admin goes to blank screen after forwarding URL

Question

i have wordpress multisite setup on my LAMP here at home (static ip address) Using my ip in any browser it seems to work flawlessly (i have four subdirectory network sites running on it) This evening i went over to one of my domain registrars and forwarded the domain name to my static ip address (clone method).

unfortunately, if i navigate to my wordpress site using the URL/wp-admin, i cannot access the dashboard on any of the network sites (it just shows a blank screen in the browser). The various networked sites front ends appear to be working normally although the login meta doesnt work (its does absolutely nothing...as if there's no hyperlink)

So essentially, static ip address method of getting to multisite works fine... URL forwarding = no login to dashboard using meta or wp-admin... but everything appears to work on the front end

any ideas?

Answer 1

I have had the same issue on each multi-site I've installed.

When you set up the multisite network for WordPress you were asked to copy some code into the .htaccess file.

Change the following line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule (wp-(login|content|admin|includes).*) $1 [L]

The first line will ONLY work on the main site url. The second line adds wp-login to the list of acceptable wp folders/files and loads them relative to the root. The problem with this is rule is that it does not matter where these components appear in the url - you can write a blog post with the url '/how-to-use-wp-admin/' and the website will internally attempt to redirect you to '/wp-admin/'. What are the chances of that, though?
