[solved] I guess this is a configuration question.
I move my site (Joomla 3.8, Kirigami theme installed with rocketlauncher) to a subdirectory. This is so I can use it as a reference while I recreate it fresh in the main directory. Fresh meaning without the rockerlauncher demo things and my messes from learning.
I moved it to the subdirectory using info. from
docs.joomla.org/Moving_the_site_among_di...ries/sub-directories
(for config file)
forum.joomla.org/viewtopic.php?p=1454615#p1454615
(moved instead of deleted)
I also moved the Layout directory to the subdirectory.
The site shows a single ">" and the page source is:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-gb" lang="en-gb" >
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<jdoc:include type="head" />
</head>
<body <!-- Unable to render layout... can not find layout class for doc_body -->>
<div id="rt-page-surround">
<div id="rt-drawer">
<div class="rt-container">
If I change the theme in the database to protostar then it works.
What is needed for it to find the RocketTheme things?
