404 Error when clicking ADD new

Did you set your permalink to post name or do you have a custom permalinks ?

Permalinks is set to Post name

I have changed them back to default now but still getting the error

1. Are you able to get to “add” page through frontend dashboard? When you’re logged in you should see “Manage my Downloads” link in /cmdownloads/ list.
2. Can you send the URL of your site?
3. Can you allow access to admin panel so we can check what’s wrong there?
If you don’t want to send those data (points 2 and 3) publicly you can send it via e-mail.

hello, i have the same problem. when i click on the add new button or link, it always shows 404 error page. i installed the newest version 1.3.5 can you help me solve this problem?

I have this debug trace (if it helps):

Warning: Cannot modify header information – headers already sent by (output started at /media/melodi/http/wordpress/wp-includes/functions.php:2925) in /media/melodi/http/wordpress/wp-includes/pluggable.php on line 876

my problem has been solved. I just need to change the permalinks to post name

I also get this error when clicking ‘Add New’ and have my permalinks set to post name.

I am running wordpress within IIS so I received an IIS 404 error mentioning the required directories didn’t exist. I manually created them and am now receiving a 404.20 error instead.

Is there anything I could try that has been previously reported?

Thanks in advance.
