After every skin I install, on each of the browsers I use, I get the following error messages above the actual wiki:

Warning: fopen(pub/cache/Site.StyleSheet.css) [function.fopen]: failed to open stream: Permission denied in /f1/content/.../public/pmwiki/cookbook/stylepage.php on line 105

Warning: fclose(): supplied argument is not a valid stream resource in /f1/content/.../public/pmwiki/cookbook/stylepage.php on line 107

Warning: Cannot modify header information - headers already sent by (output started at /f1/content/.../public/pmwiki/cookbook/stylepage.php:105) in /f1/content/.../public/pmwiki/index.php on line 1079

Please could someone explain what this is all about?

The wiki loads and works as normal (as far as I can tell), but this stuff just spoils it.

This looks like a problem with a recipe: Cookbook:CSSInWikiPages which supplies the file stylepage.php. You may want to ask the recipe author there. --Petko? July 12, 2009, at 07:22 PM
