I cannot see the option to enable WordPress custom fields, and no, I have not installed or used Advanced Custom Fields Plugin for WordPress. I also disabled my functions.php (just in case) but with no luck. How can I see custom fields to enable it?
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
I mark this as answered. Go to any page or post and click on edit and follow the arrows below.
By default, the custom fields option is hidden on the post edit screen. To view it, you need to click on the three-dot menu at the top-right corner of the screen and select ‘Options’ from the menu. Reference: this site
