Ok, since there seems to be absolutely no response to the plea for a complete working copy of mod.comment.php, the next question would be: can I simply replace the system files for 1.6.8 with those for 1.6.7 (for which I do have a backup of the install files), or do I have to start over from scratch? Or, to put it another way, are there any significant changes in the database schema between the two versions?
Any help on this question deeply appreciated!
