I had my website all set up and working and installed the same theme onto a sub directory on my website to create a 2nd portfolio page (the theme I was using wouldn't let me do this in the main theme site).
For example: my website is http://www.angieburgess.com
I installed wordpress again with the same theme under http://www.angieburgess.com/portraits
Now I am unable to log in to my main wordpress site and it has completely disappeared showing error message: Error establishing a database connection
The strange thing is I had installed a 2nd theme onto my site in a subdirectory (angieburgess.com/Gallery) yesterday and it worked fine, infact it is still working... so its not the new pages but installing the same theme again - Can anyone suggest how to fix this problem.
Many thanks in advance!
P.S. I'm relatively new to WP, so explanations in the simplest language would be much appreciated.
