I set up wordpress on my laptop and it works fine.
I have copied all my files across to my pc and now I get the 'Error estabishing a database connection'. I am using WAMP and I have worked on wordpress sites before on my pc before.
I'm not 100% sure how to check ports. I left clicked on wamp/Apache and it says that port 80 is being used by Apache, which I assume is correct.
Please can someone help?
