Orstio ... you win the prize!!!
I went back and reinstalled the sef.php file from the Joomla zip file, uploaded it and it works.
I guess I
thought I ha in d returned the file to its original state, probably because I
thought I only commented out line 386 of sef.php and uncommented line 392 of the same file. Either I did something else awhile back and don't remember or I corrupted the file.
I do appreciate your patience in helping me solve this matter.
As soon as I go live with my SMF forum I'll be making a financial contribution.
Many thanks!
