404 Error on Wordpress /lists and lists/admin

Postby essent » 6:40am, Mon 30 May, 2011


I've followed all the steps and changed the config file etc but when I try to go to /lists I get a 404 error. I have checked the permissions as per another thread and double checked I have the ;'s and ".s in the config file. Any help greatly appreciated :)

The problem here was that your sever did not like the line: php_flag magic_quotes_gpc on in the lists/.htaccess file, adding the "#" to the line thus: #php_flag magic_quotes_gpc on and reasaving your .htaccess file, fixed the error.

Your error trapping in your main site's .htaccess file trapped the 500 error which was caused by the magic_quotes setting, and you were redirected to your 404 error page.

Make the change, save the file, and issue sorted.

You just remove your htaccess file, but remember to keep backup of your .htaccess file.
Now go to admin section and deactivate permalinks option. After doing this you logout.
So again login and activate the permalinks option, after this an .htaccess file will automatically created.
And there will be no problem of 404 error.
Kind Regards!

Hi, everyone.
I'm getting the same error, that's why I'm posting here. Hope I'm doing right.
I've been trying to setup phplist on the same host as a wordpress installation: www.belgranostudio.com.ar,
but when I try to initiate it in http://www.belgranostudio.com.ar/lists/admin/, I get the error. You can see it for yourselves.
Have you managed to solve this?

Thanks in advance!.

Hi again!
I've managed to sort it out.
I had to comment out the last line of the htaccess file.

This can occur when one app situated in a directory below uses a Rewrite Engine to control the error process, as WordPress does. It frequently happens when the phplist (or an other app) has a password protected directory. Apache's implementation of Password Protection utilizes a call to an error 401 (Unauthorized) as part of the authorization process. This process get hijacked (by in this case WordPress) and the authorization has no chance of occurring. Since many have Password protection enabled as possibly the admin directory or one of its files, and they long since authorized their computer, folks often forget that this is a factor.

In this case, a solution is not to alter your WordPress .htaccess, but to use the root phplist's .htaccess (not the list/admin/.htaccess, but list/.htaccess) to regain control. Adding the following as necessarily the first statement in your .htaccess should do the trick:
Code: Select all
#Added line below to prevent WP from hijacking the URL in the Authorization Process
ErrorDocument 401 default

This is a common problem and I thought it worth bumping a rather old post as it is still an issue I see several times a month.

Hope this helps!
