[Loris-dev] Blank white page

You should also ensure that the directory (and any parent directories) have the executable bit set.

(The executable bit means that you can "enter" the directory, which the web server requires in order to read

the file..)

Hi Alfredo,

It sounds like your file system permissions are preventing config.xml file from being read, as they prevented writing to it during installation.

If you reset the ownership on your (new) loris root path:
 sudo chown -R lorisadmin.lorisadmin /var/www/loris

and then verify and restart your apache configuration steps<https://github.com/aces/Loris/wiki/Installing-Loris-in-Depth#configuring-apache2>, does that help?

If not, can you run and send the output of this command:
> ls -l /var/www/loris/project/

Best,
Christine

Hi Christine,

I moved the code to /var/www/loris and changed the 'Base' and 'DownloadPath' in the database. After doing this I had to go again though the db installation (installdb.php). At the end of this step I got a webpage saying:

----------------------------------------------------
Almost done! The LORIS username was configured, but the web server wasn't able to write to the file /var/www/loris//project/config.xml. Please copy and paste the following into that file on the server in which this web server is running or contact your system administer for help: <?xml version="1.0" encoding="ISO-8859-1" ?>
... </config>

After that you should be able to access LORIS by visiting http://132.206.178.78<http://132.206.178.78/> and logging in with the front end admin username and password you configured on the previous page.
----------------------------------------------------

After that modification in the config.xml file I am still not able to access http://132.206.178.78 , I get a blank page (the variables Base has the right path in the new database that I had to create). Moreover if I go to http://132.206.178.78<http://132.206.178.78/>/installdb.php I can still start the database configuration process, before it was saying that an instance of LORIS was already configured.

Here is what I have in the apache log (/var/log/apache2/loris-error.log)

[Mon Nov 06 12:05:39.773502 2017] [:error] [pid 16522] [client 170.223.207.30:23171<http://170.223.207.30:23171>] PHP Fatal error:  Uncaught ConfigurationException: Config file config.xml does not exist in the defined locations. in /var/www/loris/php/libraries/NDB_Config.class.inc:146\nStack trace:\n#0 /var/www/loris/php/libraries/NDB_Config.class.inc(73): NDB_Config->configFilePath()\n#1 /var/www/loris/php/libraries/NDB_Factory.class.inc(118): NDB_Config::singleton(NULL)\n#2 /var/www/loris/php/libraries/NDB_Client.class.inc(54): NDB_Factory->config(NULL)\n#3 /var/www/loris/htdocs/main.php(29): NDB_Client->initialize()\n#4 {main}\n  thrown in /var/www/loris/php/libraries/NDB_Config.class.inc on line 146

Any ideas?

Best,
Alfredo.

Hi Alfredo,

Can I just move everything one folder up (mv /var/www/loris/LORIS/* /var/www/loris)?

Yes, it's recommended to just move the code one directory up, to /var/www/loris/

The clone command you executed should have used a period as the last argument -- to clone to the current directory.  (I'll see if we can clarify that in the wiki.)

When reading the troubleshooting section (https://github.com/aces/Loris/wiki/Installing-Loris-in-Depth#troubleshooting-the-basic-installation) it is specified to check the 'base' path, but this path has not been declare before. Maybe it is a well known path in apache, but I don't know where to find and modify it.

The Base path is a Loris Config table setting -- usually accessible from the front-end Configuration module, under the "Paths" section.
Given that your front-end is not loading, follow the detailed config troubleshooting instructions in the wiki<https://github.com/aces/Loris/wiki/Project-Customization#troubleshooting-configuration-settings> to modify this setting from the MySQL back-end.

Dear LORIS Dev Team,

I just finished the installation of LORIS but when I go to <loris-url> I get a blank white page! I think this is related to the way I got the code from git. In the instructions (https://github.com/aces/Loris/wiki/Setting-Up-Git) it is written to run:

-------------------------------------------------------------------------------
Run cd /var/www (Or where your apache2 is serving files from)
Run cd <loris-directory>
Run git clone <git-clone-url>
Wait while it clones
Clone complete
-------------------------------------------------------------------------------

This leaves the LORIS code in the folder:

/var/www/loris/LORIS

However, later in the installation process (https://github.com/aces/Loris/wiki/Installing-Loris-in-Depth#configuring-apache2) the instructions make reference to the folder

var/www/<project-name>

All that to say that I think Apache is trying to access /var/www/loris but the real path is /var/www/loris/LORIS.

When reading the troubleshooting section (https://github.com/aces/Loris/wiki/Installing-Loris-in-Depth#troubleshooting-the-basic-installation) it is specified to check the 'base' path, but this path has not been declare before. Maybe it is a well known path in apache, but I don't know where to find and modify it.

Could you help me this issue?
Can I just move everything one folder up (mv /var/www/loris/LORIS/* /var/www/loris)?

Thank you for any help.

Regards,
Alfredo.
