Just installed WP v 3.5 and I do not have other themes nor do I have any plug-ins. I was simply trying to upload a logo into my media library which is a supported graphic format. The following is what I did:
Clicked on the <<Media>> tab from WordPress version 3.5 then clicked on <<Browse>> and I selected a .png graphic file and then clicked on the <<Upload>> button and received the following errors:
Warning: stream_get_wrappers() has been disabled for security reasons in /www/zzl.org/s/t/r/websitename/htdocs/wp-includes/functions.php on line 3830
Warning: join() [function.join]: Invalid arguments passed in /www/zzl.org/s/t/r/websitename/htdocs/wp-includes/functions.php on line 3831
Warning: Cannot modify header information - headers already sent by (output started at /www/zzl.org/s/t/r/websitename/htdocs/wp-includes/functions.php:3830) in /www/zzl.org/s/t/r/websitename/htdocs/wp-includes/pluggable.php on line 876
There was no directory under wp-content called "uploads", so I created this directory and then chmod it to 777 and I'm still receiving this error message. I'm using the theme "Twenty Twelve"
