    Upon installation of version 3.3.3, I go to my admin site and get the following error:

    Fatal error: Class 'iaAbstractControllerBackend' not found in /hostPATH/admin/index.php on line 28

    Issue has been resolved via helpdesk. By some reason .htaccess has not been uploaded to the server. It's hidden by default, and on some system it's not visible when you unpack zip package.

    I have the same issue, but my hosting is on Nginx with the latest PHP. Installation was failing as well, because of the wrong link was generated (http://host/install/install/configuration), but I've managed to make it happen. I can log-in, but when I select the Admin Dashboard it gives me the same error.

    Code (Text):
    2015/06/02 07:43:52 [error] 25373#0: *3235 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Class 'iaAbstractControllerBackend' not found in /hosting/subrion/admin/index.php on line 28

    It looks like your admin panel controller is used directly. It should be routed via root/index.php. In this case you won't have the issue you have now.
    I suppose this condition might be the cause of the issue you have:
    check this .htaccess rule:
    RewriteRule ^(.*)(\.php([0-9]*)|\.json|\.xml|\.tpl|\.phtml|\.ini|\.inc|/)$ index.php?_p=$1 [NC,QSA,L]

    Try to forward your traffic to root index.php file. Let us know if it works. Thanks

    I'm glad to advise :) Could you please share the final working nginx config, so other users could use it on their nginx setup?

    We definitely need an instruction somewhere here to avoid problems with Mac users.

    This issue should have been resolved in our latest version. Please let us know what version you currently use. We also need to know your PHP version installed on your server.

    Hello @alexmtz.g,

    The possible reason of this error is in missing .htaccess file.
    Please try to upload .htaccess file to root folder of your web server (near admin/ includes/ and other folders)
    I've attached zipped .htaccess file, you should unzip it.
