The exact version required for eZ Find + eZ Publish 4 should be PHP 5.1.6 . This is the version bundled with RHEL 5, and we've got very strong incentives for supporting this version.
Thanks for your reply. I thought exactly so. I was trying to get it running with PHP 5.1.2 and came across several errors, but since the version could be blame for those, I'll try to update my server first.
Don't hesitate to post the errors you got here. Even though we don't officially support 5.1.2, we always want our solutions to work on as many setups as possible.
Thanks, but too many things were wrong with that installation, so I decided not to air it after all ;) And it seems that I will not have to move back to 5.1 anymore.
But now I think I have checked everything I could with the new one, it seems like few steps further, but still not through - I moved it to a new topic: http://ez.no/developer/forum/extensions/ez_find/ez_publish_4_alpha2_classes_are_not_available
