Blank page when trying to install

[Rey]

Hello, I have a VPS server with CentOS 6.8 64 bit installed.
I had successfully downloaded and extracted Abantecart v1.2.9. Now when I go to the /install/ directory via browser, I get the first page absolutely fine(The License agreement page) but when I click Next to go to the Compatibility Validation page it just shows a blank page. No error or anything.
I had even turned on PHP error reporting but still no info or error.
Can someone please help in this regard?

Thank you.

is something in httpd. error log ? i mean /var/log/apache2/httpd .error file

There is nothing in httpd error logs nor php error logs, have already checked. I am really lost, been banging my head into this since past 2 days.
Have 4 other websites hosted on the same server, but they all are working fine.

Please find attached more info about the server, please see if it helps.
Thank you.

looks like output buffering disabled for php (or ob-lib for php does not installed on server. not sure. i use debian based linux. )

Please check output_buffering directive inside your php.ini file.

Code Select Expand

output_buffering = ON

also you can check it via phpinfo(); function

[Rey]

Using phpinfo(); Output_buffering is shown as 0 | No Value.
In php (dot) ini output_buffering is Off. Should i just change the value to On or any other numeric value?

Thanks.

[abolabo]

yes. you should to enable it.
Switch value to 1 (or "On")

[Rey]

Enabled output_buffering, restarted httpd, still same blank page on pressing continue from the license agreement page. No progress

[Rey]

I am sure there must be other people with the same issue? Anyone please?

[abolabo]

Enabled output_buffering, restarted httpd, still same blank page on pressing continue from the license agreement page. No progress

cause is in output buffering 100%.

Try to add

Code Select Expand

   phpinfo();  exit;
into first line of your /install/index.php file after open-tag "<?php" and check it via browser.

[Rey]

output buffering master value is shown as 1. I had enabled it via php . ini.

[abolabo]

ok. let's debug together.

Please replace file public_html/core/helper/utils.php
with attached.
i added var_dump there. You will see output of headers list. please post it here

[Rey]

Got this as output after replacing core/helper/utils.php with the one you provided.

[abolabo]

hm.... it must be different.

ok.. please replace again (see attach)
will be output buffer content
