Displaying JOOMLACAPTCHA rather than captcha image

[austega]

Hi all,

after working fine on my registration form for a month or so, the
captcha display now shows JOOMLACAPTCHA rather than the captcha image.
CAn still change font colour etc but can't reset the dispay etc. Am
using J1.5.10 and have installed (and uninstalled and reinstalled)
JC4.5.1 and the associated J1.5.10 patch.

Site is nswagtc.org.au - only application is on Create a Account ie
user.register. I will leave it with the error situation showing for
the next day or so, but will have to turn it off after that if the
problem is not fixed.

I am at a loss to explain this sudden not working, but cannot find any
reference elsewhere to the problem.

Thanks.

May be you enabled caching? JC4.5.1 Not Compatible With Joomla! System
Cache Enabled

[austega]

Thanks for the reply. I did have the system cache on, but have turned
it off, closed the FF3 browser and reopened it and still the same
problem. Is there any other factor I have missed?

Global Configuration -> Session Settings -> Session Handler
Try to change these settings.
Try to clear Cache.
Problem which you encountered is related to the processing sessions.
I once encountered a similar case. Then, each page is requested twice
because of some additional modules. This was in the previous version
of Joomla.

Thanks again. Scary stuff. I changed the Session Handler from database
to none and the session time from 60 to 2, closed browser - and then
could no longer log into the backend at all - no error message just
did not recognise the login name and pw. Had to edit the
configuration.php to recover. What am I missing and what is going on?
I have disabled the captcha to allow new users to register (and of
course the bots).

Remembered. The JC stores its session files.
In order not to depend on the mechanism of the sessions of the
program.
This is the basis of security and guarantees for the code module.
Test parameter "session.save_path" in "php.ini" and
сheck that the directory is available for recording.

When the displayed image module, it reads the code from the file
session.
For example
http://nswagtc.org.au/plugins/system/captcha/showcode.php?1243692643&sid=qsu32l8ibimfs8vdqrnfoipvc2&crt=0&clr=255,255,255&bgr=196,196,196&xsize=100&ysize=40&suf=2
will look for a file with name "qsu32l8ibimfs8vdqrnfoipvc2" in the
directory of files of sessions ("session.save_path" in "php.ini")

If you displaying a page with a picture as soon as another session
then the problem is likely in the redirection, ie the re-sending the
page server.

Try to set up a test site

Thanks again Kupala, now fully working.

My session_save_path folder was not writeable and this had not caused
a problem before because I had session_handler set to "database". So
problem was at my end, though of course it might be good to document
this in your documentation.
