Site unreachable after IiiItems plugin activated

[pguerr061703]

I installed this plugin to my Omeka site hosted a Linux virtual host, and as soon as I activated this Omeka plugin, the site became unreachable: (Blank page)..
I checked /var/log/httpd/error.log and getting quite a frew PHP Fatal errors.
Can someone please suggest how to resolve this.
I'm on a Redhat 6.9 virtual host running Omeka version 2.5. I tried to get this plugin to work on 2.4.1 and still get PHP fatal errors

@pguerr061703 Please try the fix-php54 branch and let me know if it unblocks your site.

Link: https://github.com/utlib/IiifItems/tree/fix-php54

[pguerr061703]

unzipped the fix-php54 in /var/www/html/omeka/plugins folder. Ensured its owned by apache:apache. Restarted HTTPD service and went to my Omeka site plugin page, the plugin says "This is not a invalid plugin". I am trying to get this iiif-toolkit-with-mirador plugin to work, but it keeps hanging my Omeka site
http://omeka.org/add-ons/plugins/iiif-toolkit-with-mirador/
See attached picture

[pguerr061703]

[dicksonlaw583]

Please remove both plugins, then unzip the download from fix-php54 and rename the resulting directory to IiifItems.

[pguerr061703]

The plugin is installed, but when I activate IIF Toolkit and click on the "Items" tab in Omeka, I get an error: Zend_Db_Statement_Mysqli_Exception Mysqli statement execute error : No data supplied for parameters in prepared statement

[dicksonlaw583]

Can you copy-and-paste the error so that the part hidden by the scroll bar is visible?

Also, can you access individual items from Collections? If you can, can you access an item from there, go to its edit screen and check if there is an item type named "Annotation" there?

[pguerr061703]

Below are the errors in its entirety. Yes I can access the Collections Tab, and I see Annotations(see pic below)

Just an FYI, When I click on IIF Toolkit button and click on Status tab, I get a different error as well

It appears that the tables and entries added by the plugin are missing from your installation. Can you uninstall and then reinstall?

[pguerr061703]

I uninstalled IiifItems, removed the plugin, and copied the IiifItems-fix-php54.zip back to Omeka plugins folder, unzipped and renamed to IiifItems, changed owner and group to apache:apacheusers ...Now when I click install from Omeka interface, I get an another error:

Please update the background.php.path key in your Omeka installation's application/config/config.ini file to match the actual path to your PHP binary. If you are on a shared host or institutional server, please consult an administrator for advice. All background-running jobs, including the plugin's installation routine and IIIF manifest importer, rely on this setting.

Here is a similar discussion from the old Omeka forums for another plugin, running on BlueHost: http://omeka.org/forums-legacy/topic/csv-import-plugin-not-working-on-shared-host

[pguerr061703]

I'm a little confused. What am I pointing this background.php.path path to? php or php-cli ? (see below)
[root@edl-myd01 config]# rpm -ql php-cli-5.4.45-12.el6.remi.x86_64
/usr/bin/phar
/usr/bin/phar.phar
/usr/bin/php
/usr/bin/php-cgi
/usr/bin/phpize
/usr/bin/zts-php
/usr/share/doc/php-cli-5.4.45
/usr/share/doc/php-cli-5.4.45/README

/usr/share/man/man1/phpize.1.gz
/usr/share/man/man1/zts-php.1.gz
[root@edl-myd01 config]#

[dicksonlaw583]

Try pointing it at /usr/bin/php.

[pguerr061703]

That didn't work either. Somehow its complaining about php-cli, which I do not have

[dicksonlaw583]

Can you show the output of the following commands?

• which php
• php -v

[pguerr061703]

[root@edl-myd01 config]# which php
/usr/bin/php
[root@edl-myd01 config]# php -v
PHP 5.4.45 (cli) (built: Feb 18 2017 15:55:26)

[root@edl-myd01 config]#

[dicksonlaw583]

What happens if you point it to your /usr/bin/php-cgi instead?

[pguerr061703]

I honestly don't know what the problem is. Same result

[dicksonlaw583]

Change it back to /usr/bin/php for now. I'm running out of leads as well, but here are a few more things to try and find the cause:

• Check for exec in disable_functions from phpinfo.
• su into the apache user account and try running php -v from it.
• Debug line 123 application/libraries/Omeka/Job/Process/Dispatcher.php and watch the value of variables representing the command and output.

These won't fix the problem on their own, but will give valuable insight into what might be wrong.

If the setup still doesn't work, I would recommend removing IIIF Toolkit for now and ask on forum.omeka.org for help setting up background jobs. Some batch-editing features of Omeka rely on dispatching background jobs, and they will likely trigger the same errors on your current setup even without the IIIF Toolkit plugin. You can retry installing the plugin later once jobs are setting off properly.

[pguerr061703]

I suspect this plugin does not fully work or is supported on Omeka 2.4.1 or 2.5. I tried multiple times to uninstall on a different host, and I cannot.

After clicking Uninstall button

[dicksonlaw583]

I have just pushed up a more fault-tolerant uninstallation routine that recovers better from interrupted installations. Can you re-download the fix-php54 branch and try again?

[dicksonlaw583]

@pguerr061703

Were you able to uninstall the plugin? Your feedback would be appreciated.
