Errors in MarketPress 2.4 — Store Settings Errors – Just Upgraded

I just upgraded to MarketPress version 2.4. I believe there are two errors with this new version that has just been provided.

1. Message Settings: Store Settings > Messages Settings

Error: There is no SAVE button available after making edits & changes. For example, I need to change the Store Admin Email (immediately) and there is no way to SAVE the changes.

2. Message Settings: Store Settings > Store Pages

Error: I do not recall any fatal error message before. I now see this following Fatal Error message in the Store Pages section that states:

"Fatal error: Call to undefined function wp_editor() in /home/content/49/8697049/html/wp-content/plugins/marketpress/marketpress.php on line 5528"

Not sure what that is or what it means or what the problem is.

Can we you let me know what to do to fix these problems. I need to get this fixed immediately.
