Hello,
I perform the data integrity test to clean the database.

After a while, I have the "Fix" button that appears.

I use the "fix" button
it runs for a while, then after an error message.

Looking in the logs we find this:

2023-02-02 15:34:11.252 CET [32469] ERROR: syntax error on or near "LEFT" at character 43
2023-02-02 15:34:11.252 CET [32469] INSTRUCTION: DELETE FROM "lime_quota_languagesettings" LEFT JOIN lime_quota q ON lime_quota_languagesettings.quotals_quota_id=q.id WHERE (q.id IS NULL)

I have broken down the query as follows:
SELECT * FROM "lime_quota_languagesettings" LEFT JOIN lime_quota q ON lime_quota_languagesettings.quotals_quota_id=q.id WHERE (q.id IS NULL)

first result: I have rows with NULL and others not

we continue :

select * from lime_quota_languagesettings as lime1 where lime1.quotals_name IS NULL;

I have NULLs for name

but I did not find a NULL id

And the last :
select * from lime_quota as lime1

I put in screenshot the results of the 3 queries,
I don't understand the syntax error.
