You need to give permission access to the www-data user or group (Apache)

[misaligar]

I don't have www-data on the host. I don't have Apache or any other web server installed on the host machine.

How do I give permission to www-data in the FreshRSS container?

See the permisisons within the docker container:

docker exec freshrss ls -alh /var/www/FreshRSS/extensions
total 280K
drwxr-xr-x 3 1000 www-data 4.0K Nov 18 09:19 .
drwxr-xr-x 1 root www-data 4.0K Nov 18 15:30 ..
drwxr-xr-x 4 1000 www-data 4.0K Oct 31 07:17 xExtension-CustomCSS

I was able to fix the issue by running the commands in an earlier discussion

https://github.com/FreshRSS/Extensions/issues/37#issuecomment-1363474585

Any thoughts how I ended up having the wrong permissions in the very first place?
