We have got the latest PHP version on Hostsharing, and Knowledge Tree 3.7.0.2 did not work anymore.
I got a long list of deprecated warnings, and the session would not even start, so not even a login screen is displayed.
Deprecated: Assigning the return value of new by reference is deprecated
Warning: The magic method __get() must have public visibility and cannot be static
Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent
The solution is to edit config/dmsDefaults.php, find the lines containing
error_reporting(E_ALL & ~E_NOTICE);ini_set(‘display_errors’, ‘1’);ini_set(‘display_startup_errors’, ‘1’);
Below that, add the following line:
error_reporting(0);
Now Knowledge Tree 3.7.0.2 will work again, and hopefully the next version of Knowledge Tree will have fixed all the deprecated PHP things.
Knowledge Tree and PHP 5.3.3
Thank you. Made my night a couple of hours longer.
How did you find out?
Saludos

BTW: If the wizard doesn’t let you install KT on php 5.3 just change a line in /setup/wizard/steps/dependencies.php
change phpversion to 5.4 or something. 🙂
Many many thank you man
Hi I have followed your tip on my PHP 5.3.10 server but now on
myknowledgetreesite/control.php
I get a blank screen 🙁
Can you advise? Thanks!
a blank screen is usually a sign for a typo. Check your changes again. Otherwise modify your php.ini to show errors (display_errors = On), which might help you to find the line of your typo.
Hi I have double checked the edit. When I remove the line
error_reporting(0);
I will get output on the page like this:
Deprecated: Assigning the return value of new by reference is deprecated in etc etc etc
I definitely don’t have a typo – when I put it back in, the whole screen shows a blank 🙁
I did a
tail -f /var/log/messages
and reloaded the page (and get a blank)
but it does not show any errors
You can also try to use error_reporting(E_ERROR);
see also http://php.net/manual/en/function.error-reporting.php for possible parameters.
On the other hand, I am quite disappointed with KnowledgeTree, since it seems they are not developing the community version anymore. See also this thread: http://forums.knowledgetree.org/viewtopic.php?f=3&t=20951
I am personally considering to try Alfresco, but I have not found an easy way yet to migrate my documents with versioning to Alfresco.
On my server, Apache/2.2.9 PHP 5.3.3-7 Debian, I needed to fix the error_reporting in /etc/php5/apache2/php.ini too.
By the way, it is not needed to set the error_reporting to 0, “E_ALL & ~E_WARNING & ~E_NOTICE & ~E_DEPRECATEDE_ALL & ~E_WARNING & ~E_NOTICE & ~E_DEPRECATED” (in both dmsDefaults.php __and__ php.ini) will do the trick.
