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

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.
output_buffering = ON
also you can check it via phpinfo(); function
-
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.
-
yes. you should to enable it.
Switch value to 1 (or "On")
-
Enabled output_buffering, restarted httpd, still same blank page on pressing continue from the license agreement page. No progress :(
-
I am sure there must be other people with the same issue? Anyone please?

cause is in output buffering 100%.
Try to add
phpinfo(); exit;
into first line of your /install/index.php file after open-tag "<?php" and check it via browser.
-
output buffering master value is shown as 1. I had enabled it via php . ini.
-
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
-
Got this as output after replacing core/helper/utils.php with the one you provided.
-
hm.... it must be different.
ok.. please replace again (see attach)
will be output buffer content
-
btw, can you send response body for your blank page?
i mean html-code by CTRL+U press shortcut
-
This is the output after uploading second utils file.
-
There is nothing in the page source as well. The page source is completely blank too.
-
what about session settings in php. i mean session cookies.
Do you see it saved in your browser?
Is session id the same after page reload?
Probably session set cookie via http-headers and sends some data every time on request.
Please check it. Just open license-page and do refresh. Note session id in cookies before/after load.
-
Yes, I see cookies.
There was 1 cookie named: PHPSESSID
There were 2 cookies named : PHPSESSID_AC
1 cookie named: default
and 1 cookie named: install_0b073fcfe1b0
I reloaded the page many times, the value of the cookies was not changing.
I cleared the cookies and reloaded the page, now there is only 1 new cookie PHPSESSID_AC, whose value is different than the previous PHPSESSID_AC cookie.
Thanks.
-
what about public_html/system/logs ? Is something there?
Yes, please find attached.
Thanks.
Was this fixed? There is a space somewhere in your file before <?php tag
Can you attach your utils.php file in here?
-
No it was not fixed. I still see same error in system/logs.
Which file should I check for a space before <?php tag?
I am using the same utils.php which was attached by abolabo in previous posts.
Thanks.
-
Can you please attach your core/helper/utils.php file in here?
-
try to add this
ob_start();
after opened-tag <?php inside file /public_html/install/index.php
it must to enable buffering anyway
-
@eCommerce Core please find attached the utils.php
@abolabo Finally, I can reach the settings page after adding ob_start(); in /install/index.phpBut still it shows that Output buffering is off(please see attached image), but I have turned it on in php.ini and phpinfo(); too shows that OB is on. It is very confusing now..
Thanks.
-
...as i told
so you should to check all php,ini files in your centos.
not sure how many it. In debian based linux stores few. For apache, for shell-mode (cli) etc.
You should check what file applied. The better way to see it in phpinfo(); output in browser.
Also be sure that echo output_buffering=On without ; at the line begining (not commented)
-
Thanks. As far as I know, there is only one php.ini which is being used at the moment.
I will double check again and report back. Thank you for helping out. :)

Yes, as stated above, I managed to reach the next page after adding ob_start(); at the top of this page - /install/index.phpInstallation went successfully after doing the same.
