The Omeka Site is Not Uploaded Right when Installed

I would like to know why is that my homepage was getting this error:

Warning: require_once(Zend/Loader/Autoloader.php): failed to open stream: No such file or directory in /home/naturo12/public_html/dragontreaurelibrary/bootstrap.php on line 145

Fatal error: require_once(): Failed opening required 'Zend/Loader/Autoloader.php' (include_path='.:/usr/lib/php:/usr/local/lib/php:/home/naturo12/php') in /home/naturo12/public_html/dragontreaurelibrary/bootstrap.php on line 145

Please check this on my site: since somehow when i contacted my hosting company, they say "(get Omeka to) have a look something with the installation isn't referencing the zend installation properly, you might try contacting the support of omeka to find out how you might tweak this setting

these appear to be the possible options:
# find . -name Autoloader.php

Please let me know what my hosting company mean by this and if you happen to spot the error, please fix it for me and on the Softaculous site so that I can start developing my webpage.

The new site address that I changed to is

My first guess is that either not all of the files were uploaded to the server (in particular, bootstrap.php), or the files are there, but not readable by the server. I'd check that all the files were uploaded okay, and that the permissions are set correctly.

Hi Patrick,
I would like to know what version of PHP will the server fnd Omeka 2.3.1 readable since I found out through my hosting company that the problem was the server side on their end.

Hi Patrick,
The version that my hosting company has for their server end was a 5.6 I wonder if there is any version of Omeka that will work for such server?

Also I would like to know which file are missing in the server that makes it appear the error it appear since I am totally new to this app.

Also, on the update for my site on Omeka, I found that my site is still experiencing error even after I have downgraded my site from that of a PHP 5.6 to a 5.4 and still experiencing problems. Please let me know what is going on since it has been happening from the first time I installed Omeka.

Omeka 2.3.1 works fine with both PHP 5.4 and PHP 5.6.
