Hi guys, my PC crashed but managed to recover it.
When i restarted wamp it gives an error on line 14....

I renamed the folder and reinstalled it again and its working now

Question is i have my site saved and the original files with the DataBase
Which and where do i find the files to restore/relocate to new folder

I want to use the database/site of the old install on the new install.
