For some reasons two of my site (fakoplast.nl en michorius.com) are not showing up anymore.
I didn't change anything last month but for some reason I get the following error:

Fatal error: Cannot redeclare readfile() in /home/vgsnp/domains/fakoplast.nl/public_html/lib/misc.functions.php on line 1093

I am using: PHP Version 5.2.8

What is wrong?and how to fix. I already updated to the latest version but the error still exists!

greetings,

Could be your hostingprovider does not allow readfile script on php. Had the same problem with mine.
Probably you should check your provider
