I installed Modx through the built-in hosting download and there are generated files in the files index.html , mchost.php , index.php , config.core.php . What to do with index.html ? I thought to rename it, but it turned out to be impossible inside the "files" tab -the field with the name is not clickable. And what are the rest of the above files intended for?
index.php from MODX is critical and necessary, it's the entry point. config.core.php contains path to the MODX core, also necessary file out of the box. The rest do not apply to MODX, you can delete them.
