Describe here your question/suggestion/issue (expected and actual results):
I am a little bit stuck as I am using a default 'ubuntu' user name but still it does not carry enough privilleges for me to change the file permissions, see below:
bitnami@ip-111-11-1-111:/opt/bitnami/apps/wordpress/htdocs/wp-content/themes/Extra$ chmod 777 footer.php
chmod: changing permissions of ‘footer.php’: Operation not permitted
Should I be sudo'ing? I thought the default permission level of 'ubuntu' should be sufficient? Any ideas? Thanks for your help!
