Re: Fatal errors when upgrading to 15.2

posts: 98 Greece

I attempted once more to upgrade from 12 -> 15 with not success. This time from 12.11 -> to 15.4. I had hoped the newer versions would be more kind to me, but not.

So It is the same fatal error after I try to connect db to my wiki folder:
Fatal error: Uncaught exception 'TikiDb_Exception_DuplicateEntry' with message 'Duplicate entry found
and a few more lines like these in the first mesage above that conclude in
/lib/core/TikiDb/Exception.php on line 13

Just the day before I upgraded 12.9 -> 12.11 with no problem whatsover. So it looks like the problem has to do with the 12 -> 15 transit. I should solve it or I am stuck with 12...

How I do the upgrade each time, in case I am mistaken.
(a) I rename old folder
(b) unzip new version in a folder with my site's working name
(c) run the installer from there
(d) connect to my db

I don't do any export - import of db, I just reconnect the existing with the new folder.

Any hint?
