Hi there, I finally upgraded from 2.0.2 to 2.0.4 and immediately hit an error message, before even running the upgrade file (but I did press upgrade).
I got the following error message:
Warning: fopen(/home/petite/public_html/wordpress/wp-content/cache/wp_cache_mutex.lock) [function.fopen]: failed to open stream: No such file or directory in /home/petite/public_html/wordpress/wp-content/plugins/wp-cache/wp-cache-phase2.php on line 79
Warning: Cannot modify header information – headers already sent by (output started at /home/petite/public_html/wordpress/wp-content/plugins/wp-cache/wp-cache-phase2.php:79) in /home/petite/public_html/wordpress/wp-includes/pluggable-functions.php on line 272
as instructed in teh codex, I deleted the content/cache folder (and this wasn’t backed up at all)
What can I do to fix this error message, any ideas? Something of an emergency!
