Menber can't see the edit button

One (I'm sure all) of my members can't see the edit button. I can see it just fine but why can't they see it?

Hi,

You probably have it set where that specific group isn't allowed to edit their own posts.

Go to :
ACP => General => Forum => Categories and forums => click the permissions button to edit a forums permissions, then click the Advanced Mode button.

From there you can modify the editing permissions.

Members cannot edit other peoples posts only there own posts and I'm not sure if it's for a limited time only. Moderators can edit people's posts on category's that you let them edit. 

I hope that answered your question if you need anymore information I'll take a look on your forum and join.

If you can help me fix it that would be great. Let me know and I will send you the link via pm.

Do you have an image for the edit button?

Administration Panel > Display > Colors & Pictures > Pics Management
Advanced Mode
Buttons Tab

Yes I have a button but I'm the only one who can see it.

Is this happening on the whole forum or a certain section?

The whole thing.

Ask the member to use a different browser to see if it could be his/hers browser?

Hello,

Make sure your enabling them to edit their own posts on permissions(as suggested above)   
AP > Categories and Forums > Click permissions   :
Click advanced mode:
Edit its own message : Checked for members
> Save

Apply this to all forums.
