Supplier Invoices - Duplicate entry '1' for key 2

Installing my Dolibarr
1

Please help, I’m in trouble here. This week I found that I can no longer validate a supplier invoice, Dolibarr keeps returning the message Duplicate entry ‘1’ for key 2. It happened in 3.8.0, then I upgrade to 3.9.0 but I still have the same problem. Can anyone offer any advice about my problem? I am falling behind on invoice processing now.

I am not a programmer, so I hope there is someone who can tell me a simple step-by-step way of solving this issue.

Thanks in advance for any help I can can get.

Try to calk page /install/repair.php

Did you install any external module ?
Does your database is mysql or postgresql

I’m sorry but I don’t understand fully. I am not an IT guru.

The issue started after many succesful months using 3.8.0, with no other app installs. To try and rectify the issue I installed 3.9.0, however the problem remains.

I am using standard install. I believe my database is mysql type, but how can I check (keeping in mind I am a mechanical engineer, not a software engineer :cheer: )

hello Eldy,

Do you have any further suggestion about how I solve this problem? I’ve been two weeks without being able to enter supplier invoices now.

Thanks in advance for your help.
