Database must be updated. - Nothing to be updated

[Caesar]

Hello,

I just updated Hoteldruid from ver. 2.3.2 to ver. 3.0.6 and did exactly the update steps as described in the Readme file. After all files were transfered I went to https://...../inizio.php and it showed "Database must be updated." So I hit the button and then came this message: " HOTELDRUID version 3.0.6, Copyright (C) 2001-2023 Marco M. F. De Santis
HotelDruid comes with ABSOLUTELY NO WARRANTY;
for details see the file COPYING.
This is free software, and you are welcome to redistribute it
under certain conditions; see the file COPYING for details.

Nothing to be updated."
Then I hit the button Go To Main Menu and it asks me again "Database must be updated."

I can't go anywhere now. I made a backup before the version update. How can I resolve it please?
Thank you kindly/Mille Grazie!

Cheers
Caesar

Ok, after going back to the old version and installing each and every following version I'm finally at the latest version 3.0.6.
The only issue I have now is that I can't go to the years 2014 and 2017 anymore. All other years are working fine (and worked before the updates).
It tells me:
"Availability from
Warning: SQLite3::query(): Unable to prepare statement: 1, no such table: periodi2014 in /home/tutu/public_html/booking/ov1/includes/funzioni_sqlite.php on line 82

ERROR in: select datainizio,datafine from periodi2014 where datainizio <= '2024-05-31' and datafine > '2024-05-31' "
And:

"Availability from
Warning: SQLite3::query(): Unable to prepare statement: 1, no such table: periodi2017 in /home/tutu/public_html/booking/ov1/includes/funzioni_sqlite.php on line 82

ERROR in: select datainizio,datafine from periodi2017 where datainizio <= '2024-05-31' and datafine > '2024-05-31' "

Any help would be highly appreciated.

Cheers
