For those people finding it difficult to upload the database.sql, here is the fix. Like I said, I found some foreign characters in that file.
You have to delete this foreign characters and re save it, then re-upload it. If you have uploaded this file in your database earlier on, Please drop(delete) the old file before uploading the updated file.
I have uploaded the fixed database.sql for version 2.2 as database.zip.
Things to NOTE
You can't install this script in a folder extension of your url. It must be installed as a main site like this
www.yourdomain.com
Or you install it as a subdomain
www.subdomain.yourdomain.com
If you installed in subdomain, you must create an email in the subdomain, then use the subdomain SMTP email settings for the script to send and receive mail.
I did a lot of research to enable me fix this annoying issue.
