DOMDocument issue following upgrade from 3.4.4

Did a dry run upgrade this evening to 4.0.5 from 3.4.4 and no elements in the system now display (tickets etc).

Error is:

ERROR : Impossible to load class DOMDocument
=> Not found in ../model/DOMDocument.php
=> Not found in ../model/persistence/DOMDocument.php

Correct you are many thanks.

For anyone else with the issue, this is caused by replicating an install / DB to a new folder on the same server. You'll need to kill HTTPD once this is done to flush it out.

Hi,

I have exactly the same issue but I can't solve it.

I wish to have a test environment so :
- I copied the database from my main installation (Project'Or RIA 3.0.2) to a new database.
- I installed ProjeQtOr 4.0.5 on the same Apache/PHP server as my main installation.
- Both installations use the same domain name/port (http://myserver/projectorria et http://myserver/projeqtor-test).

After I noticed the issue, I found this topic so I stopped the httpd service, deleted all the PHP sessions in /var/lib/php/session/ and restarted the httpd service.
But the issue is still there.

I also tried to change the PHP session id by adding the line session_name("PHPSESSIDTEST"); before session_start(); in manual/manual.php and tool/projector.php.

Finally, I created a virtualhost on port 8080. But it didn't help (maybe because the domain name is seen as the same by Apache).

Do you have an other idea to solve this ?

Thank you for your quick answer.

I found the error. I lacked the php-xml module.
The use of DOMDocument class seems to have been introduced in v4.0.0, that's why I don't have this issue on my main environment (which uses v3.0.2).
I installed php-xml module and everything is fine

Edit : If it can help, this module is not installed by default when you install PHP 5.3 on a RHEL server ( v5.8 ).
