shortcode is shown instead of form

This is what is shown on my page :

[wpuf_form id= ?279″]

The correct format would be [wpuf_form id="279"]. Switch the editor to “text” mode and insert that shortcode. Also try to find out if any plugin is conflicting with your site or not.

Hi Tareq Hasan & thanks for your reply.
I inactivated all the plugins one by one… no result ??
I also pasted the shortcode to text editor… no result ??

I paste the correct shortcode : [wpuf_form id=”279″] but on the page instead of form I have the modified shortcode like : [wpuf_form id= ?279″]

How cad I resolve this problem ? Perhaps with another plugin for frontend publishing ? any sugestions ?

Thanks in advance,

resolved !!!!!!

I have two folders for wordpress files, one is www/, another is www/subfolder. I copied the plugin folder into both wp-content/plugins & ………… It works !

Thank U again for your replies ?? ?? ??
