Cannot access Post when it matches Category name???

Hi,

I’ve never seen this before, it’s weird, can someone please help???

I have permalinks set to: /%postname%/, I cannot choose that, but I just select the ‘Post Name’ option in Settings Permalinks.

I had some previous HTML pages on the website, one in particular had the same name, but with .html on the end, as the post I was trying to create.

Now, the problem. I created a post that had the same name as a category that was already setup, so it was like this:
/MY-POSTNAME/

I had a category: /MY-POSTNAME/ already in place.

When I saved the Post, I could not go to that page, the page does not load and over and over I get a message in firefox about redirection and cookies. So, I renamed the Category to: /MYPOSTNAME/ (without the dash). That should be fine right?

Still, the post would not load. Getting over and over again, the error about redirection/cookies in Firefox, in IE get nothing but loading spinning, and then nothing… finally at some point in Firefox getting 404 error.

So, back to the post, renamed it with a ‘2’ on the end, Pressed Ctrl-F5, the Post would load, so back to the post, changed it back to: without the 2, so now it would be: /MY-POSTNAME/ and it did load fine.

So, thought problem solved. WRONG. Edited a few more times, changed things. Then back to view the page, same thing: redirection/cookies error in Firefox, over and over again.

So, back to change post name to: /MY-POSTNAME2/ (note the ‘2’ on the end), it worked, so finally decide to change it to: /MY-POSTNAME1/.
It works, and loads.

Now the HUGE PROBLEM. WHY is it that I cannot change the postname to: /MY-POSTNAME/ and load that page in my browser?

WHY does WordPress keep failing to load that Post? Over and over again, remember the category is now name /MYPOSTNAME (without the ‘-‘).

WHAT can I do to change the post name back to the original name that the category had: /MY-POSTNAME/? Is there some .htaccess things I can change (file below)?

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

That’s a standard htaccess.

Oh, and YES, I have tried deleted the old Posts and adding new Posts, and also viewing those OLD posts in the Trash that I had deleted, and then Deleted Permanently.

Nothing seems to have any effect???

IS this a WordPress bug?

Thanks,
