Hello guys i am using the wfchannel module and i have a little problem with the permission.I create a page called Test i give the permission to (Test) to viewed by Webmaster's Registered Users and Anonymous.The problem is when some guests login to the site can't read the (Test page) and get the message :

Sorry, you don't have the permission to access this area.
If the page does not automatically reload, please

In debug mode in http://www.site.com/modules/wfchannel/

i get the message:
Warning: xoopsOption[template_main] should be defined before including header.php in file /footer.php line 68

And from http://www.site.com/modules/wfchannel/admin/permissions.php admin panel when i go to permissions i get this message :
Notice: Only variables should be assigned by reference in file /class/xoopsform/grouppermform.php line 144

i am using XOOPS 2.0.16
Thanks a lot.
