Help with wordpress permalink structure

I am using this permalink custom structure for my wordpress - /%postname%.html

I have success with it in my blogs but lately on the new wordpress blogs that I have I am having some problems...
Everytime I write a post, it automatically puts number 2 at the end...like it would end up like this

this-is-my-post-2.html...

I dont have duplicate post title so I dont know why it is doing that..

please help.

 

check your slug.

 

you mean the category slug?

 

anyone else who can help with this problem?

 

Set to default and than save, after that change and set one more time to your structure and than save!

 

I use /%category%/%postname%.html on all of my blogs and it does the job.

 

Have you checked to see first whether you have another blog post with the same title, and secondly, a blog post already published which has the same permalink? I always use /%post_id%/%postname%/ because even if you have a post with the same title, the /%post_id%/ will differentiate them.

 

Check the Custom Permalink Structure. I believe you have changed it by mistake and added a 2 at end.

I do the same.

 

i think you are making some mistake...
okk try this in Permalinks custom - /%postname%/

and check your settings....

thanks...
if you need more help than PM me..

 

Yes, this way can improve WordPress performance too. I always use this permalink structure.
