Hy,  
in admin apper this:

The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running “occ db:add-missing-indices” those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster.

- Missing index “share\_with\_index” in table “oc\_share”.
- Missing index “parent\_index” in table “oc\_share”.
- Missing index “fs\_mtime” in table “oc\_filecache”.

Ok say run … noproblem but after ssh command:

```
sudo -u myuser php occ db:add-missing-indices
Content-type: text/html; charset=UTF-8

An unhandled exception has been thrown:
TypeError: Return value of OC\AppFramework\Http\Request::getScriptName() must be of the type string, null returned in /home/***/public_html/lib/private/AppFramework/Http/Request.php:796
Stack trace:
#0 /home/***/public_html/lib/base.php(154): OC\AppFramework\Http\Request->getScriptName()

#3 /home/***/public_html/console.php(46): require_once('/home/***/p...')
#4 /home/***/public_html/occ(10): require_once('/home/***/p...')

```

**_Solution?_**  
Thx!

For my this solution work perfect:

>
> I’ve updated to NC14 and I need to run occ db:add-missing-index but I am on Synology NAS and don’t have the ability to run occ command How can I do ? How can I add those indexes with SQL request ? Index "share\_with\_index" missing on table "share" Index "parent\_index" missing on table "share" Index "fs\_mtime" missing on table "filecache" Thanks Regards, Delor3an

I not use tablename  
`" __nextcloud__"`

simple add directley in myadmin  
 ![](https://i.imgur.com/KhkkOM7.png)

```
ALTER TABLE oc_share ADD INDEX share_with_index (share_with) USING BTREE;
ALTER TABLE oc_share ADD INDEX parent_index (parent) USING BTREE;
i added this:
ALTER TABLE oc_filecache ADD INDEX fs_mtime (mtime) USING BTREE;

the rest Warning and error resolve in cPanel WHM

So far, the first line was sloppy  
Add lines 2 and 3 to the apache setting

```
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" env=HTTPS

Header always set Referrer-Policy "no-referrer-when-downgrade"

Hi,

Can you just try:

```
sudo -u myuser php /home/***/public_html/occ db:add-missing-indices

```

What PHP version are you using?  
Can you check your folder and file permissions again?

It does not work and 7.1 php is used in the cpanel because it is not work with 7.2 … while it is allegedly compatible and if I switch to 72, the whole thing dies.  
And os centos latest v.

Is the first question @all solved?  
If so - please do me a favour and list your steps!

If not … I’ve got the same problem!

Hi @JimmyKater

Can you post your error messages again? What’s written in the nextcloud log?

> [@JimmyKater](#):

OK 🙂  
Change directory to your NC installation folder (probably /var/www/nextcloud). Then run:

```auto
ls -lR | grep -E "^dr|^-r" | grep -v "`ps -ef | grep apache | grep -v root | awk '{print $1}' | sort | uniq`"

```

Not a nice command, but I don’t know your web server user 😛

1.

The database is missing some indexes. Due to the fact that adding indexes on big tables could take some time they were not added automatically. By running “occ db:add-missing-indices” those missing indexes could be added manually while the instance keeps running. Once the indexes are added queries to those tables are usually much faster.

 Missing index “share_with_index” in table “oc_share”.
 Missing index “parent_index” in table “oc_share”.
 Missing index “fs_mtime” in table “oc_filecache”.

```

2.` The “Referrer-Policy” HTTP header is not set to “no-referrer”, “no-referrer-when-downgrade”, “strict-origin” or “strict-origin-when-cross-origin”. This can leak referer information.`

i guess this could be solved by this [thread](https://help.nextcloud.com/t/the-referrer-policy-http-header-is-not-set-to-no-referrer/36613) (haven’t tried it yet, though)

That’s probably not the right thread. In the earlier versions the header needed to be added manually, but with NC 14.0.4 the header was added already. Usually, the check fails, if the header is set twice.

Please check here if that’s the case and the header is really set twice:  
[https://securityheaders.io/](https://securityheaders.io/)

If it’s set twice, this might probably help:

> I also had this issue. I had Header always set Referrer-Policy "no-referrer" in /etc/apache2/conf-available/security.conf. Replacing with Header set Referrer-Policy "no-referrer" and restarting Apache and the warning goes away. Now what does the “always” option do?

Or removing the header from one of the locations. I’m currently trying to find the many threads that were opened recently. If I find them, I’ll post them here.

For the DB part, run:  
`sudo -u www-data php /var/www/nextcloud/occ db:add-missing-indices`

Here we go:  
the other solution is, to remove or comment the header setting from the apache config file (/etc/apache2/apache2.conf):

> [@The "Referrer-Policy" HTTP header is not set to "no-referrer"](https://help.nextcloud.com/t/the-referrer-policy-http-header-is-not-set-to-no-referrer/36613/43):

To remove it from the .htaccess now, doesn’t make any sense to me, because it will be added by nextcloud with every update. Removing `Header always set Referrer-Policy "no referrer"` from apache config should be more future-proof.

Did you update the app groupfolders to the latest version right before?  
When I wanted to run occ to find out the correct commands for the DB index I noticed that occ didn’t run on my server as well. For me this issue occured with the last groupfolders update.

I “solved” that issue by moving the “groupfolders” folder out of /var/www/nextcloud/apps/; i.e.  
`mv /var/www/nextcloud/apps/groupfolders ~/`

**Edit:** Issue with groupfolders confirmed:

at least now the add-command runs through.  
so that solved MY problem with the db as well. thanks.

how do i mv it back? or would a new installation of it be better?

i need to check the other error on like tomorrow. i’m sure there’s a solution as well.

thank you very much for your help!!! i really appreciate it

I don’t suggest moving version 2.0 back in. On github the users are reporting heavy server load and log file flooding.  
Best is probably to wait for the next version and install the new and fixed version from the app store. I’ll do that this way.

And yeah, the other message will probably disappear as soon as you comment out one content-policy-header setting.

i commented that out like this:

```
#<IfModule mod_headers.c>
# Header always set Referrer-Policy "no-referrer"
#</IfModule>

```

but somehow it seems that it didn’t work out the way we expected it because the error didnt vanish

Hi Jimmy,

can you run your site through [securityheaders.com](https://securityheaders.com/) and see whether it says something along the lines in the “Warning box”

`There was a duplicate.....`

If there is, this is causing the message `Header always set Referrer-Policy "no referrer"` to appear in your admin panel.

I had the same issue and checked in the apache configs as well as in the nginx configs and the .htaccess. I agree with Schmu, I would leave it in the .htaccess since NC is always adding it there with each update you do.

thanks @CFelix for joining in here 🙂

i ran my site through the link you provided and it came up with the following warnings

> Warnings
> 
> | Content-Security-Policy | This policy contains ‘unsafe-eval’ which is dangerous in the script-src directive. |
> | --- | --- |
> | Referrer-Policy | There was a duplicate Referrer-Policy header. |

and this missing thing

> Missing Headers
> 
> Feature-Policy [Feature Policy](https://scotthelme.co.uk/a-new-security-header-feature-policy/) is a new header that allows a site to control which features and APIs can be used in the browser.

ummm. noob-question: where do i find the ngix.conf, usually?
