[Solved] problem upgrading on live server

[ieftin-net]

I am trying to upgrade from 1.0.0.8 to 1.4.3
all went fine on my local server, but when i tried to upgrade the live version i got this

ERROR!
One or more errors have occurred, you can find more informations below or in the log/installation.log file.

Error during install/upgrade: 

You may have to:
1.Fix the error(s) displayed
2.Put your database backup
3.Modify the file settings.inc.php to put the old version for the line with _PS_VERSION_
4.Restart the upgrade process from the begining

in the log file i only got this

*ERROR*     2011/06/22 - 19:19:53: 5

since i can't see any error displayed, i don't know what to do at step 1.
i have tried to follow steps 2, 3 and 4 but i got the same error.

you might try to take a baby step approach, and upgrade to v1.2 or v1.3 first. that error you are getting is really not very helpful at all

I would move the database to your local server and upgrade it there (remember to copy the settings.inc.php from your old Prestashop version on the production server too). You can then create a new database on the production server and populate it with the upgraded version you've prepared locally. Ideally when upgrading a production site you should be able to roll back to the previous version (in the event of a problem) instantaneously. I would always have both versions (code and database) online and switch between the two.

I have tried that before but always had problems.

I solved the problem by uploading to the live server the upgraded version [data plus db] from the local server and simply modifying the settings.inc.php

thanks, and i hope this helps other people
