Hi @DanielW ,
Our cloud images are configured with the user
bitnami, so it is necessary to switch to that user in order to modify the file you are trying to. To do that, please run the commands below that will switch to that user and then open the
vim editor, but you can use your preferred editor instead.
sudo su bitnami
Please let us know if it worked for you or if you have any other questions. You can find more information about Mediawiki for Google Cloud in our documentation website at https://docs.bitnami.com/google/apps/mediawiki/
