the suggested solution to your problem has been pointed at several times already and this suggestion was meant to be expressed by the link to this same page. It is this:
You should not use the "Install" process to upgrade an old copy of OJS -- it has likely garbled your database. You need to follow the instructions in docs/UPGRADE. I would suggest restoring your database from a backup made prior to clicking the "Install" button and proceeding from there.
You have still not said a word about this yet but kept asking for help to fix your problem. In the quote above is the start of help to fix your problem.
