I'm getting this error when I change the template on a local install:
fread() expects parameter 1 to be resource, boolean given in xampp\htdocs\wordpress\wp-includes\functions.php on line 4455
Also this one:
Warning: fclose() expects parameter 1 to be resource, boolean given in F:\Program Files\xampp\htdocs\wordpress\wp-includes\functions.php on line 4458
Looks like they're related.
Never had this problem before. Anybody have any ideas?
