WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Child Theme. ” Internal Server Error” when creating new pages., by Steve Stern Meaning you start a child theme right from the beginning, with a clean father theme? right. You never did anything manually or used Child Theme Configuration plugin after changing the father theme? I used the plugin once just to see what it did. I prefer the manual methods because if something breaks, I know it’s something I did and don’t have to dig through plugins to see what they might have done. (edit)… that should be “when something breaks” Reply To: Child Theme. ” Internal Server Error” when creating new pages.
