Hi All, since my provider stopped PHP7.4 they moved to 8. With my current install Alpha 17.0.0 (15.0.03) I received too many errors running Dollibar. It still worked though just very ugly to work with. I tried to upgrade to 16.0.1. and i got this message upon pressing the log in button/ Unknown column ‘u.note’ in ‘field list’ how to fix this? thanks Albi ---

Hello, Basically, you have a V16 program with a V17 database. It will create a lot of issues. > [@Can't disable install tools after upgrade to 16 "UPDATED"](https://www.dolibarr.org/forum/t/cant-disable-install-tools-after-upgrade-to-16-updated/22782/10): > > Hello, This means that the note column doesn’t exist in llx\_user table. Most probably it is due to the fact that your DB is now in V17 : In V17, the note has been rename to note\_private Using a V17 Database with V15 program won’t work. If you do not have a V16 backup, then you need to install a fresh V16, and re-create everything (or import/export) ---

i dont have V16 backup since i wanted to install a V16 on the V17. Is it possible just to overwrite all htdocs again with V17 and it will work or needs a complete new install and import of V17? ---

V17 is in development, should not be used. ---

this is too late now, my latest backup is from V12.0.03, then upgrade to the V15.0.03 because of the PHP 8 issues. This turned out to be the V17. So what to do the V12 update is more than a months old. still my answer was if i can just overwrite everything in htdcos with 17 and it will work again or will the error remain? thanks ---

V17 is unstable, so you will not have the same issue, but you will probably get others… ---

somehow it is running now again once i overwrite all htdocs with V17. Is there a way to downgrade the 17 to 16 without having a 16 backup? ---
