# Error msg – clear old database tables

 * I’m upgrading 2.7 and trying to keep my old wp-config file. When I went to the
   install script I got this message:
 * “You appear to have already installed WordPress. To reinstall please clear your
   old database tables first.”
 * I didn’t have many posts so I don’t mind losing them and restarting. What’s my
   next step?
 * Thanks in advance.

 * Use wp-admin/upgrade.php (not install.php) if upgrading.
 * [Upgrading WordPress](http://codex.wordpress.org/Upgrading_WordPress) has the
   process.

 * Thanks, Michael. Actually, I tried to do a fresh install but kept the original
   wp-config file. Everything else was new.
 * I tried the upgrade.php script like you suggested and got:
 * Fatal error: Call to undefined function wp_remote_post() in /hsphere/local/home/
   steveand/sima-wisdom.net/wp-includes/cron.php on line 201
 * This usually means some files didn’t upload right, but I went through and meticulously
   compared files to make sure they were all there. What next?

 * The function `wp_remote_post` is in wp-includes/http.php so try uploading that
   file.
 * If that doesn’t resolve, recommend you redo Steps 7 and 8 of [Upgrading WordPress Extended](http://codex.wordpress.org/Upgrading_WordPress_Extended).
 * Make sure when [Uploading WordPress to a remote host](http://codex.wordpress.org/Uploading_WordPress_to_a_remote_host)
   that you are using ASCII file transfer mode (or AUTO mode in FileZilla).

 * I had this problem. I looked everywhere. MichaelH, thank you so much!
