Permissions Error 7.10

[Gretsch]

Trying to get WHMCS on CentOS 8. I get as far as getting LAMP installed and working as far as I can tell. But when I go to the install page, I get errors saying the permissions are not correct on some of the files and directories:

Read/Write Permissions	File/Directory Path	Help
Configuration File	/configuration.php
Attachments Directory	/attachments/
Downloads Directory	/downloads/
Templates Compile Directory	/templates_c/

When showing these permissions in the OS I show the following:

-rwxrwxrwx.  1 apache apache      0 Aug 14 11:54 configuration.php

-rwxrwxrwx.  1 apache apache 167636 Aug 14 11:54 install.php

drwxrwxrwx.  2 apache apache     23 Aug 14 11:54 attachments

drwxrwxrwx.  2 apache apache     23 Aug 14 11:54 downloads

drwxrwxrwx.  2 apache apache     23 Aug 14 11:54 templates_c

The path to my directory is /var/www/html/whmcs. Does this need to be in a different location and the permissions errors are because the installer is not detecting the permissions correctly? Or are the permissions incorrect in some way I am not seeing. Maybe I don't have a php module installed thats needed to make this work? Modules I have are:
