Unfortunately not. :-(

Firstly prior to last Thursday all was working fine with any version of
Moodle.

At one point last night it looked like whatever the clash is didn't exist
with Moodle 2.x but I then tried with a version of Moodle 2.3 and that had
the same problem. Also as I mentioned there are lots of people using moodle
for authentication and I'm sure keen to get xot 1.9 with the xenith code etc
but many won't be able to upgrade from Moodle 1.9 yet for all sorts of
reasons.

I've read over the posts, thanks for all the work you guys have put in to
this.

Would it be fair to summarise that things work fine in Moodle 2.x, but not
moodle 1.9?

Version 1.9 is not working either if I use the functions.php from svn. White
screen again. (When using Moodle intergration).

It's a version 2, but I don't know which one.

I also have a moodle 1.9 (but again, I don't know exactly what version). But
that one seems to work as well for me. But I have to clear cache etc, to
make sure I don't use a different session.

Where can you check the exact version of moodle?

Tom

do you have a moodle 1.9 to test with?

Your question about moodle version gave me an idea to test locally with
xampp. I'm going to say this with caution because I thought I was able to
reproduce the problem with xampp previously too but I just tested the
following:

The test install I was using with xampp was using a moodle2 config path and
not giving the same problems as the linux servers. So I just change that
config path to a moodle 1.9 install and it did then give the same problems.
I then changed the config path back to a 1.9 install and the problem is
there again.

So not forgetting that the Techdis server install has been working fine with
a moodle 1.9 config all this time it seems this indicates the following:

a recent XOT code change has introduced a clash with moodle 1.9 but not
moodle 2?

the problem can be reproduced on Windows via xampp if moodle 1.9 is avilable
to add as the integration_config_path

In theory I could upgrade the Moodle on the techdis server to a later
version because we aren't using that install for anything else but that
doesn't help people who want to upgrade xot but can't yet upgrade their
Moodle and it doesn't really help identify the specific
change/cause/solution either.

However maybe it's easier to track down with xampp?

As far as I can see the last change to the zend folder was 29/04/2012

On both installations I've been testing the moodle is 1.9x What about yours?

Yes, but is the Zend folder changed recently? (I am currently not behind my
PC, so can't check)

I did have a situation where MySQL statements took so long, that the
workspace was not complete. But then you would have to have 10ths of LO's in
your workspace.

Can it have anything to do with the version of Moodle used?

Also as far as I can see the last change to /trunk/functions.php was a
change you made on 23rd of October Tom way before these problems started.

I changed functions.php and restarted Apache but it hasn't fixed the create
new project issue for me.

You had a blank screen previously - could this be a separate issue? 

Did you ever see the create a new project workspace clears issue?

It's working for me now.

And whether you have to restart apache depends a bit on whether you have
eAccelerator or something active. Sometimes it helps to restart apache
(php).

Hi Tom

unfortunately this doesn't fix it for me :-(

I've cleared cache and restarted the browser but still the same problem.

Does that change require an Apache restart?

Did you get to a point where you were no longer getting a blank screen and
seeing the workspace clear when creating a new LO?

Ok...

I've got it working here, if I change line 48 of functions.php

$language = new Zend_Locale();

To 

$language = 'en-GB';   (and yes I realize it is doing something else)

If this also works for you, than something has changed in the Zend
installation.

Somewhere in tracing through the constructor of Zend_Locale I end up in
moodle_request_shutdown() .....

Hi Tom

yes so for example /var/www/moodle/config.php 

or on shared hosting might be /home/user/public_html/moodle/config.php

Not sure why you get a blank page - at least I get to see the workspace! ;-)

If you change authentication to moodle and restart the browser do you get
prompted to login to moodle? If you do then the path you have entered is
correct.

Ron,

Just to be sure, in step 6, this is the full Linux file path to the moodle
config.php, right?

It is definitely not working, I get a blank page, until I remove the config
path from the sitedetails page.

Nothing shows up in the debug.log, not in the apache errorlog, and nothing
in the javascript console.

I will try to start all this in the debugger (xdebug).

There are two other issues in my install:
1. Sometimes the editor disappears behind the browser window.
2. In a Media page with an image, preview, all is fine, now close preview
and try to select a different image....

Hi John

I can't help with a VM but here's the steps to replicate...

1. Create a directory in the web root and copy across an export from the
latest svn trunk e.g. xot19

2. Create a new database and user with the relevant privileges or use the
mysql root account if only a test

3. Browse to /xot19/setup/ and follows the tests or go straight to
/xot19/setup/page1.php

4. During setup add the admin account credentials (whatever you want) and
leave integration_config_path empty

5. Upon completion browse to the xot19 url which by default should be guest
access and create a couple of tests LO's

All should be fine at this point.

6. Visit /xot19/management.php and add the path to moodle config.php

7. Now whether you leave authentication set to guest or change it to moodle
you should see the problem with creating new LO's etc. I'll send a link to a
screencast of that later.

Hi,

I had a go at setting up on a Ubuntu VM on VirtualBox at the weekend but ran
out of time and into problems figuring out where to put passwords into the
database using phpMyAdmin, setting up the integration path etc.

If someone wants to share a VM which exhibits the problem and share it then
I'll definitely take a look at debugging.

Hi,

Starting a new thread on the current issues with the integration path stuff.
I'm afraid my own technical knowledge doesn't go far in the relevant areas,
but it is clear that we have a problem that needs resolving before we can
make the Xenith code available to everyone, and it seems to me that recent
changes have introduced the problem. Ron has done a lot to try and isolate
the problem, thanks a lot for persisting Ron! 

Somehow we need to resolve it. I'm open for ideas on how we can best work
through it: in an ideal world I'd get Ron to sit with Pat at a computer
until the problem is cracked, but since that's not possible, is this
something we can do online somehow? Anyone got any better ideas?

Julian
