[cacti-user] Can't save anything trough web interface

Hi,

I did an upgrade from 0.8.8g to 1.0.4 and it went quite well, I can login
to the web interface, graphs are updating, but I can't make any changes
through the web interface.

For example if I go to Settings, and try to change the path for the cacti
log, hit "Save" and the page reloads with the old path still showing.

Same happens if I try to delete a device under "Devices". I select delete
under "Choose an action" and the page reloads with the selected devices
not deleted.

OS RHEL6
PHP version 5.6.30
MySQL version 5.1.73
Apache 2.2.31

Any ideas what might be wrong? The database user can definitely write to
the db and I don't get any errors in any logs. Any help appreciated.
