KREST api gives blank page, Rewrite tested, works

Timo12357 · February 15, 2017, 9:24am

Hi
We are using SuiteCRM 7.8.1 on a Ubuntu 12.04 LTS server.

Installing Kreporter fails at the KREST api install:SuiteCRM/KREST/sysinfo returns a blank page.

mod_rewrite works, tested it like this: http://old.webasyst.net/support/help/general-modrewrite-test.html
set folder permissions according to http://support.sugarcrm.com/Knowledge_Base/Platform_Management/Required_File_System_Permissions_on_Linux/index.html

What next?
Timo

Hi Timo, which php version do run on Ubuntu 12.04? The php 5.3 included in Ubuntu 12.04 package is too old for KREST. An Upgrade to php 5.6 would be best.

Timo12357 · February 15, 2017, 1:44pm

Maretval,
we used to run php 5.3, but I upgraded as per your kind instructions. Now the server runs php 5.6. I am sorry to inform, that KREST still gives a blank page

Timo

maretval · February 15, 2017, 2:29pm

Timo, please check

php.ini settings: display_errors should be set to Off
httpd.conf or any subconfiguration for your webserver shall AllowOverride All
Example:
DocumentRoot “C:/htdocs”
<Directory “C:/htdocs”>
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Require all granted
</Directory>

Timo12357 · February 15, 2017, 3:03pm

I think they are in order, below snippets from the configuration files:

/etc/php5/apache2/php.ini

; Possible Values:
; Off = Do not display any errors
; stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
; On or stdout = Display errors to STDOUT
; Default Value: On
; Development Value: On
; Production Value: Off
; http://php.net/display-errors
display_errors = Off

/etc/apache2/sites-enabled/000-default

<VirtualHost *:80>
ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory />
            Options FollowSymLinks
            AllowOverride All
    </Directory>
    <Directory /var/www/>
            Options Indexes FollowSymLinks MultiViews
            AllowOverride All
            Order allow,deny
            allow from all
    </Directory>

Assuming your CRM install is directly under /var/www httpd.conf looks ok.
Next step is checking apache error log and php error log

Timo12357 · February 15, 2017, 8:16pm

Maretval,

yes indeed, the CRM install is under /var/www

No new errors are generated into /var/log/apache2/error.log when trying to create a new report in kreporter.

Timo

maretval · February 16, 2017, 12:00pm

Timo, anything in the apache access log? Let say to make sure file permissions are set correctly?

Any ideas what could be wrong?

Timo,
how are file permissions set for SuiteCRM and underlying folders/files? Does the webuser have permission to execute?

Val

What do you get when your call http://yourcrmurl/KREST/sysinfo in browser?

Timo12357 · August 18, 2017, 5:31pm

I get a blank page.
The same happens with http://mycrmurl/KREST/[anything]

Timo

spicecrm · August 22, 2017, 7:59pm

then you shoudl check your php error log. Most likely there is another error.

Timo12357 · August 29, 2017, 5:29am

I enabled php_errors.log according to: https://askubuntu.com/questions/14763/where-are-the-apache-and-php-log-files
When calling KREST no errors are added to the file.
Any more ideas?

Timo12357 · August 30, 2017, 6:08am

Anyone with a similar problem? Anything?

maretval · August 30, 2017, 8:17am

Open KREST/index.php, comment first line containing error reporting setting. Then try again and check php error log.
