Unable to access Web Interface

I have updated my Centos 7.5.1804 with latest updates.

I have updated my install by manually running ./daily.sh as it was not running via cron and have no errors when running ./daily.sh and ./validate.php with the exception of polling and discovery haven’t run in like 5 minutes.

Mariadb, Httpd, and snmpd are running without errors.

However, I cannot access the webgui…not even to login.

Please help!

post the output put of ./validate.php please

Here is the output while running at root user -

Working now. Just decided on its own time to start working.

Okay, you should look at what the validation was telling you may still have some issues
