How can I change page title?
Yes,of course!
Please open “plugins/categories-for-anspress/languages/categories-for-anspress.pot” then (only) translate “Question category: %s” to “Category: %s”. (Like @lucas_atkins in Share your AnsPress site link. ).
After that, (If there is not) create a “languages” folder in “wp-content” folder. then create a “plugins” folder in that “languages” folder. then copy your plugin-translated-file(s) in it. (This will allow you to update your plugins without re-translating your plugins )
