HI Alex,
I understand. I am sorry my paying jobs have been taking so much of my time from this. I shut off Akeeba AdminTools using the 2nd method shown using the following link then tried the login and it still wouldn't work.
www.joomlashack.com/blog/joomla/disable-admin-tools/
In the .htaccess area that you mentioned there is a box where I can "Allow direct access to these files". It has files in it that are like this one that end in .php "administrator/components/com_akeeba/restore.php" ..... SO I put the following SC Login php location in there but it didn't help. modules/mod_sclogin/mod_sclogin.php
Then there is another box that says "Allow direct access, including .php files, to these directories" so I added the following to there. ... "modules/mod_sclogin" AND IT WORKED even with 2 Factor turned on.
Then I removed "modules/mod_sclogin/mod_sclogin.php" from the first box and it continued to work.
So now I am free to tackle setting up JFB Connect.
Thanks so much for your help and patience Alex.
