# “Call to undefined function….”

 * Here’s the situation: I developed my local site (WP 5.0.1), and used the well
   known plugin Duplicator (latest version 1.3) to create an archive file to migrate
   it. After a successful install at my hosting company (Siteground, using same 
   WP version), I try to pull up the site, and get the above error. These is no 
   such error in the local version.
 * The function that PHP says it cannot find does exist; it is in a subdirectory
   of the parent theme. So what appears to be happening is that PHP loses its path…
   somehow.
 * Any suggestions? Am completely stumped at the moment….see the debug statements
   before the error where I attempted to print out info about the path.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcall-to-undefined-function-31%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * [http://rickcasey.net/](http://rickcasey.net/) opens fine for me, NO error.
 * However, [http://rickcasey.net/test/](http://rickcasey.net/test/) throws the 
   error.
 * That error seems to be coming from your `info1` theme, which could not be found
   in the wordpress.org/themes/ directory.
 * If this was a custom theme, you may have to go back to your developer team and
   ask them to make the necessary change(s) to the theme.

 * I fixed this problem; here was the solution.
 * For whatever reason, the theme was not quite installed correctly, even though
   the install with the Duplicator installer completely without error; but the child
   theme was showing up in the admin dashboard as a broken theme. But once I activated
   the parent theme, and rechecked the child theme in the file structure, the child
   theme showed up (magically) in the dashboard. I was then able to activate the
   child theme, and then functioned correctly.
 * Just another WordPress mystery…..
