Thanks!
Dealing with this issue helped me find another issue. First, I learned that I am missing some opencube loaders for some versions of PHP. For whatever reason, they were not downloaded when I compiled and installed multiple PHP versions from within CWP. Secondly, I learned that eXtplorer is not compatible with all versions of PHP. I downloaded opencube loaders and added a .htaccess file to the eXtplorer directory so PHP 5.6 is used for eXtplorer
