According to this source W3 Total Cache cannot detect php module if mod_php is disabled on an apache server. They also indicate that “mod_php is disabled […] by default because it is not secure (mod_php is outdated).”
Solution:
1- Verify that indeed this services are correctly activated. In order to do so run phpinfo() (see “how to run phpinfo()” )
2- Once confirmed, the error messages can therefore be ignore.
