I've just attempted to upgrade from 1.6 to 1.7 using the upgrade module and it all went pete tong (surprise), now I just went ahead and copied all the files over to do a manual install and at the dbase connection screen I'm faced with the message "At least one table with same prefix was already found, please change your prefix or drop your database" which, presumably, means I'm not upgrading but performing a fresh install, something which we can't do because we need our dbase as it's full of products and customers. I've tried going to /upgrade but it just takes me back to the dbase screen and same message. Can anyone offer any advice as to how to proceed with this, I don't want to chance overwriting our dbase, files I can handle but not the dbase.
EDIT***
As an after thought, I deleted the install folder and went straight to the admin panel (Just in case the upgrade went ahead), tried logging in and got
QuoteOops! An Error Occurred
The server returned a "500 Internal Server Error".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.
.... and now checking the cpanel I can see our Physical Memory & I/O Usage has went through the roof !! Anyone?!
Cheers
