What does this script do?
With version 1.0, I changed the file format of the database file, though only slightly. This script tries to convert the old version to the new version. Just upload a copy of your old guestbook.db file, and press "Submit" to convert it.
I just want to make sure that you understand that this script only really tries to convert your old file. If you used a custom delimiter in your script and not the default ::, it won't work. Furthermore, this seems to be impacted by filesize. I tried to convert the guestbook.db file from Kaze Ghost Warrior for testing purposes since it is larger than my own, and it did not work with my Mozilla. I tried to figure out where it went wrong, but the file just looked great to me. So, I just tried some 20 lines from the original 130+ lines file, and it worked like a charm.
Do not fear, Timothy! It seems to be browser-related as well, since the above mentioned problem does not exist with Internet Explorer, as the MAX_FILE_SIZE attribute is not really standardized, and obviously my browser chooses to ignore it. Try Internet Explorer, and it my well work for you! I do not have Opera installed at the moment, so I cannot test that.
If the script does not work in its installed version, you can download it here and put it on your server, may be it runs there. You can change the delimiter in the variable at the top. Setting a larger MAX_FILE_SIZE did not work for me, your mileage may vary.
