I upgraded from 1.5.2 to 2.0.1. After I ran upgrade.php, I click on "Have fun . ." and it takes me back to the homepage. All that's there now is "It doesn't look like you've installed WP yet. Try running install.php." I do not know why this happened. The only extra plugin I had running was lazyest-gallery and it's suposedly 2.0.1 compliant. Having 0 installation issues in the past, I did not back up the original DB files. So I have three questions:
1. Does anyone know what may fix the problem?
2. Where Can I find the old 1.5.2 zip file
3. I'm not a DB expert, so if i need to revert back to 1.5.2, will i need to cleanup any changes in the db? What feilds?
