I'm hosting wordpress on a shared hosting environment.
Somehow it would not let me edit and update the file inside wordpress theme editor(the 'update file' button is missing) and wordpress gives me this:
You need to make this file writable before you can save your changes. See the Codex for more information.
I have checked my file permission and it's 755 for the directories and 644 for all the files. If I change the files' permission to 777, I will be able to edit them in the theme editor.
How can I further troubleshoot what is wrong or do I need to contact my server admin regarding this for further information?
Thanks for the help!
