Thank you for your help and patience.
OK, I saw that NerdPack was not installing these packages so I turned them ON, rebooted and now Apache is running OK.
But I have another problem. I am trying to run phpvirtualbox, as before, and am getting (I cleared the browser cache - no help):
PHP does not have the SOAP extension enabled.
I check the php.ini file and
extension=soap.so
is OK - not commented. php.ini file is exactly the same as it was in the previous Apache version I was running.
when running:
php -i | grep -i soap
No mention of SOAP is given. Could it be that soap is missing in your package?
Can you help here as well?
