I have successfully installed the last two versions with the identical process: load sample data, clean install using installer version. No problems.
This time (0.9.17740) as soon as click through the final step of the installer, I get:
Warning: include(Mage/Admin/Model/Permissions/User.php) [function.include]: failed to open stream: No such file or directory in /home/henigson/public_html/azumahealth.com/magento/app/code/core/Mage/Core/functions.php on line 44
Fatal error: Call to a member function load() on a non-object in /home/henigson/public_html/azumahealth.com/magento/app/code/core/Mage/Install/Model/Installer.php on line 207
Same result with or without sample data; all tables seem to be in place; all files seem to be in place, etc. Something obvious, no doubt, but I’m stuck.
Thanks in advance for any help.
