Blank screen during installation

[saint42]

Greetings all,

This is a brand new SuiteCRM installation. I have gone through the other posts with similar issues before I wrote this one.

SuiteCRM 7.11.15
Apache 2.4.37
PHP 7.2.24
MariaDB 10.3.17

Apache is ran by apache.apache
SuiteCRM html folder belongs to apache.apache

All files/folders are chmod 755, the following ones are 775
cache custom modules themes data upload

There is no error message in the apache error logs
The install.log shows this;

And since there is no error message anywhere, I am at loss.
Anyone could share a hint?

Thank you.

Hello,
welcome to the community!!
I appreciate you share all basic information. Do you have anything related to this in your apache log?

[saint42]

Hi,

Apache error logs show nothing at all.
If I go to wrong pages, then I see the logs filling up, so I know this part (the error logging) is working.

The apache access log shows that I go to the install, but that’s it:
(...)suitecrm/install.php" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.1.2 Safari/605.1.15"

[saint42]

My webInspector shows that it’s calling install.php , I see the request being sent with all the information from the 2nd screen of the installation (DB, username, password, etc…) but after that no response from the server…

[pgr]

What is your distro? Are you running it with SELinux?

[saint42]

Distribution is CentOS 8
I disabled SELinux

[pgr]

I have a vague memory of CentOS requiring some extra configuration in order to let the web server write to the files (which is a requirement for SuiteCRM). Maybe SELinux, maybe htaccess… I don’t recall.

Maybe you can find some older threads in these forums with details?

Or if you can switch to Ubuntu, it’s easier for SuiteCRM.

[saint42]

I turned off SElinux … There is no error message anywhere so I don’t even know where to start troubleshooting … It’s painful.

I installed suiteCRM over nginx (still on centOS) and now have more explanation of what’s going on:

2020/09/17 14:47:21 [error] 28997#0: *9 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to undefined function json_encode() in /var/www/html/suitecrm/install/performSetup.php:53

I installed the php-json package, and it’s now working.
