I don't know whether you guys can help me with this particular issue:
I have just attempted to take a new site live on GoDaddy. I used Akeeba backup and kickstart and everything went well as far as that goes.

But on the front end www.specialed.org I get a 500 error - Cannot create css cached file in development folder: t3-assets/dev

Looking in that folder, there is no way I can identify where the problem is. GoDaddy says they can't help because it is not their server problem, it is something in that t3-assets/dev folder.

Any thoughts on who I can ask to help me with this? Thanks!

Might it be that file t3-asssets/dev was corrupted in the transfer? I used ftp to move everything. But should I delete the entire file, download the one that works from my development site and upload it, replacing one on the new server?

Try using a different folder in the template options and see if that works

the setting is in the general tab

Cheers
Paul
