Urgent issue. I went to uninstall marvikshop so I could reinstall it after I got tons of errors from moving the database from one oscommerce to the marvikshop oscommerce database. Now I get a 500 internal server error when going to the /administrator login. Please help!
Well it's not that easy. You have to import the data to the database tables. Not move the whole tables to the database!
It's easy to delete. Use a ftp program and delete the program from the root dir and the admin dir. In phpMyAdmin you can delete the j17_osc... tables. Don't forget the program rule in j17_extensions.
Delete the edit's from the two index.php files.
Now the program is deleted. You can install again.
