Yes, you are missing an option and I can't see how that would happen, since that option is actually left over from the old version. I've updated the quoteit_fix.php to fix the problem of the wrong option being selected. You can run it again to have it show the correct setting, although that's not what's causing your main problem.
To manually set the "showquote" variable, you can run this SQL query:
Code:
UPDATE $TPsetting SET value = 1
WHERE varname="showquote"
If for some reason you don't have that variable, the first query will
give you an error and you should run this one instead:
Code:
INSERT INTO $TPsetting
(varname, grouptitle, value, defaultvalue, optioncode, displayorder, advanced, volatile) VALUES
("showquote", "forumhome", 1, 1, "yesno", 5, 0, 0)
Be sure to replace $TP with your table prefix.
