Hi @ZeddenIT

If you have access to code of your Magento installation, perform following steps.

NOTE: Before making any changes in the files take backup of the files.

1) Go to errors folder in the Magento root directory
   Rename local.xml.sample file to local.xml.

   Refresh the error page in browser.
   (check if errors are displayed on front end, if no perform following steps)

2) Locate and open index.php file in Magento root directory.

Search for error_reporting(E_ALL | E_STRICT); code.
change it to
error_reporting(E_ALL);

3) Add following code line in the end of index.php file.(You may put this code line in .htaccess file also inplace of index.php file)
$_SERVER['MAGE_IS_DEVELOPER_MODE'] = true;

Also, locate the following code:

#ini_set('display_errors', 1);
Uncomment it by removing the # sign
ini_set('display_errors', 1);

Now reload the page to see errors in front end. After that you may update your question with complete error message to get any help.

Thanks for in advance for your assistance. I was unable to find the "errors" folder so searched each and every folder for the log number and came across it. the contents are below. From the first line itself i see that the database seems to be a problem. So i tried to log into the database using phpmyadmin and i get a similar message. Also index.php does not have any entry for error_reporting. Adding the line to .htaccess $_SERVER['MAGE_IS_DEVELOPER_MODE'] = true; resulted in the following message on the website
