Changes to config.php not taking effect

Good Day,

Experiencing a very strange situation. On my local dev environment version of NextCloud I updated the config/config.php with a new theme. It immediately took effect.

When I do the same on my Ubuntu server and add the theme it does not seem to take the new theme defined in my config.php.

I have checked permissions of the the folder, and it’s www-data which is what I’d expect. I have checked the log files and do not get any errors or warnings relating to config.php.

Any tips on how I can get to the bottom of this. I tried other methods like restart apache and clear browser cache just in case the theme is cached.

Thank you for any tips.

Do you use caching modules (APCu, redis)?

Yes is was a caching issue on the server mate. All sorted. Thanks
