[Xerte-dev] Re: HELP - can't create new projects on techdis install

Thu Nov 29 12:29:02 GMT 2012

as I've said I have done! But something has changed that's broken all this.

This is not the sandpit it's the test install we've been using for months
with moodle integration enabled.

With authentication set to guest or static and no value in the db for
integration path it all works.

With authentication set to guest or static and any value in the db for
integration path creating new projects doesn't work.

i would turn off moodle integation on the sandpit

See if that fixes it

Integration path is set in the db now for moodle integration and the code in

What's confusing is that this works fine via xampp but not on the linux
server and doesn't work even if the value in integration_path isn't to a
proper file/location e.g. if it's to a file that doesn't exist or incorrect
path it still causes the problem.

Could this be related to the LTI code? I've tried replacing that folder with
previous version but is that called from somewhere else that might be
causing the problem?

I didn't change integration path with my stuff? 

Ah hold on.

If you use integration path it uses the moodle session right?

Where is integration path set? 

I suspect it is moodle integration that is killing it - so the new bit I put
into config.php might be killing the integration path session.

Try moving the integration path setting towards the top of config.php

Hi all

this continues to be a nightmare but I tested some more very last night and
again this morning and I think I've got a little closer to the issue. 

I installed a brand new clean install elsewhere on the techdis server and
tried that with both guest and static authentication and with those defaults
creating new projects is fine.

However then I restored a database backup from the test installation we've
been using, edited sitedetails and copied accross the use-files and creating
new projects no longer worked. So same code but difference in db.

It seems the problem happens now when there is an integration_path in
sitedetails regardless of the authentication method used. e.g. If i switch
to guest access I can create new projects with integration path empty but I
can't with a correct or incorrect value in integration_path.

What's confusing is that this works locally via xampp with an integration
path. e.g. whether using guest, static or moodle authentication.

Also up to the point that uploading the code broke it the techdis test
installation was working fine with the integration path configured for
moodle integration. Prior to the update obviously creating new projects
hasn't been a problem.

Pat - does that help narrow the issue? 

Cheers

Ron

BTW I've noticed that deleting a project, dragging a project, creating a new
folder all have the same affect of clearing the workspace (presumably
killing the session) until refresh.

Pat/David/John

thanks for all the responses and suggestions.

I've been trying to resolve this since early afternoon and still no progress
so I'm calling it a night for now :-(

I've been updating the techdis install on practically a daily basis whenever
commits are made and until today this problem simply hasn't materialised.
e.g. after each previous update no problem creating new projects. Something
has screwed it but I just can't find what.

Maybe a new day and fresh start tomorrow will shed some light.

But it would be really good if someone else could test the latest svn code
on a linux setup rather than xampp.

Cheers

Ron

You could also perhaps add an 'ob_start()' in near the top if your problem
is actually one of spaces/the session being started too soon; this ought to
stop PHP sending headers/etc before the session starts.

Jesus. That sentence is rubbish. Well, 'the session being started too soon'
bit is at least.

'ob_start()' should delay PHP from sending any output to the browser - and
therefore may help correct any problem related to sessions. I'm pretty sure
there is an implicit 'ob_flush()' at the end of the request.

(I've rarely used ob_start()/ob_flush() so may be wrong).

David.

Also - check the Apache error log file - sometimes it has something of use.
