Hello community!
**Concrete Version:** 9.1.0
**PHP Version:** 7.4.30
I followed the instructions in the official documentation to set up an automated task for sitemap generation.
First part of the process was setting up the cron:
```auto
* * * * * /path/to/public/concrete/bin/concrete concrete:scheduler:run >> /dev/null 2>&1
```
I then added the following expression:
```auto
0 0 * * *
```
Now, when I try to access tasks via the dashboard, I am getting the following error:
```auto
/application/files/cache/expensive/0fea6a13c52b4d47/25368f24b045ca84/38a865804f8fdcb6/57cd99682e939275/2ddb27c5cdf0b672/745d4c64665be841/dc4f6a3c82dec34b/a7e4acc6325bbadb.php): failed to open stream: Permission denied
```
It seems to be related to line 46 of /concrete/src/Cache/Driver/FileSystemStashDriver.php
```auto
$result = file_put_contents($path, $storeString, LOCK_EX);
```
I’m no developer, but I would be inclined to guess this was some kind of permissions issue.
However, I’m not really sure how to fix this.
Any advice is appreciated!

I have resolved this issue. I will post the solution, as it may help others.
The fix was to change ownership of where the old root cron had written files.

The solution is to run `/path/to/public/concrete/bin/concrete` with the same user as the webserver.
If the user impersonated by the webserver is `www-data`, you can simply use
```auto
sudo -u www-data /path/to/public/concrete/bin/concrete
```
instead of
```auto
/path/to/public/concrete/bin/concrete
```

Thank you @ [mlocati](https://forums.concretecms.org/u/mlocati)
Annoyingly, that does not work for me, the scheduler does not run. I expect it is going to be a syntax error on my part, but I am just not able to work it out.
I have since started another post about the issue I am experiencing here:
