About the second question...i noticed it in JoomSef 3.7.1.
Now,i'm using JoomSef 3.7.2 and Joomla 1.5.20.
Yes...first..i follow all links in the front panel. JoomSef self-generate SEF links. After that i go in the back panel and delete the generated link to the com_contacts.
After that i return to the front panel and click over the Contacts link..and..the error you saw.
So the message appears when no link to com_contacts is generated,after that..seems to be OK..

Hi,
i'm trying to understand how could you let this error appears...



So when i delete a specific link to com_contacts generated by JoomSEF i get the following error. And after the link is generated,the message disappear. I think it's unacceptable to show error like this in the front panel. You show the structure of the database like this..i'm very disappointed from JoomSEF. How can i trust this module in that way???

P.S.
I have one more question. Why do i need to have installed joomfish to use joomsef?
When i install joomsef on fresh joomla copy,i always get the same message...it was something like..
The JoomlaControlPanel class could not be found...or something simillar.
