In this case , you can check your back-up and found the last one with biggest usage （40kb，43kb，50M） and restore the 50M back-up I dont think you deleted them if you didnt run such command, so they must be here

nav[aria-label="Primary Navigation"] { padding: 0; & ul { list-style: none; width: 100%; display: flex; flex-direction: row; justify-content: start; align-items: start; gap: 30px; padding: 0; & li { margin: 0; } & ul li { list-style: none; } } }

reboot and ./start-confluence.sh & ./startup.sh could not solve the problem

I tried using the suggested sql statement on my MS SQL server, and it says the statement is wrong. What am I doing wrong?

I tried the following statement:

UPDATE cwd_app_dir_mapping
SET LIST_INDEX=0
WHERE ID=<first_id>;

Rick Li_18uiz1

Yes to use the statement the other answer give us, we should replace the

<first_id>

with our own id ,

You can do following steps:

to connect to your database and look for the id by :

SELECT * FROM cwd_app_dir_mapping;

and you will see the id (e.g. 1200000)

Then conduct the sql:

UPDATE cwd_app_dir_mapping
SET LIST_INDEX=0
WHERE ID=1200000;

And if you have more than one rows,

just repeat the update sql until you get the list_index of the directories are in proper incremental order (i.e., 0, 1, 2, ...)

UPDATE cwd_app_dir_mapping
SET LIST_INDEX=0
WHERE ID= 1200000;

UPDATE cwd_app_dir_mapping
SET LIST_INDEX=1
WHERE ID=12000001;

UPDATE cwd_app_dir_mapping
SET LIST_INDEX=2
WHERE ID=12000002;
