Fouad, it has nothing to do with the software, check the search results in google:

or contact your hosting provider to resolve the issue. 

Ross,

I have changed the config file entry from "define('OW_DB_HOST', 'localhost')" to "define('OW_DB_HOST', '127.0.0.1')". 

Thanks for your help.

Has this resolved the issue you were having?

Yes Ross it seems to have resolved the issue.

Thanks.

Update.

I have found a new error this time relating directly to the change of the alias which means that the error can't be resolved using this method.

here is the error:

I will be reverting back to using the localhost alias until you come up with another idea of how to fix this.

Yes, you need to revert to "localhost" instead of 127.0.0.1

Also you database always get disconnected during  a simple query. 

Seems like it is constant issue, I would recommend to contact your hosting provider support team and request some explanations on that because your mysql server goes away during a simple query, it is not right.
