Hi,
If you want to display the signature, you must make sure at least these things:
1. The type of the content is checked in “Which types of content should the signature be placed?” setting.
Some content’s type is “page” rather than “post”.
2. All categories of the content are checked in “Which categories should the signature be placed?” setting.
Sometimes, a post belongs to more than one category. Make sure all of them are checked.
3. The author of the content is the one who set the signature.
More often than not, there are several authors contribute content to one site.
Make sure the signature you want to show is set by the exact author of the content,
which means the author logins using his/her account and set the signature.
4. If you have other plugins installed, maybe there are conflicts between them.
Then you can disable other plugins temporarily, and see if the signature shows up.
If signature shows up then, conflicts are confirmed.
But there still is one last try:
a. Enable other plugins again,
b. Change “The order in which this plugin is executed” on “WP Post Signature” setting page;
c. See if the signature shows up. If not, try another number.
Please don’t hesitate to update this thread again if the problem is still there.
Good luck. ^_^
