Help Finding String

Hello, I have a website running at http://www.onceuponatime.pt and I did a backup to another server and domain (www.onceuponatimewedding.eu), after the backup i needed to change some things on the database and everything seams to work except for one thing.

I get this error on the home page:

lessphp fatal error: load error: failed to find /home/onceupon/public_html/wp-content/themes/theme45886/bootstrap/less/bootstrap.lesslessphp fatal error: load error: failed to find /home/onceupon/public_html/wp-content/themes/theme45886/style.less

The problem is that on the .pt domain the username is “onceupon” but on the .eu domain the user name is “onceupo2” o know i need to change it so the path works, but I search the database and didnt find the string and also search on dreamweaver on local server and also didnt found that string.

Anyone know where I need/can change that? Is it database related or file related?

I thank you in advance for your help.
