WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Child Theme. ” Internal Server Error” when creating new pages., by johnatanasoff @sterndata @subrataemfluence I read https://codex.wordpress.org/Child_Themes carefully, and think i understood it! I know a child theme should be done right from the start, but since i already modified the parent theme; what method you recommend? 1) Child Theme Configurator plugin 2) http://techblog.kjodle.net/2014/04/...7ve_already_made_changes_to_my_original_theme I avoid using plugins, unless strictly necessary; although some are really ingenious. Have you used method 1 or 2, and can recommend me the best approach? Reply To: Child Theme. ” Internal Server Error” when creating new pages.
