I installed everything, and tried to run it and got this error...

Template error
Failed to find block 'file_line'(#()(.*?)()#s) in :

any ideas?

phpnuke 6.5

What version of coppermine are you using?

I had that same error message a few weeks ago when I installed coppermine on my site. If I remember correctly, I had to go back through setup again, and there was something wrong with file permissions.

Setup will tell you if everything is ok.
