Trying to update WP to latest version I received this message-
"Warning: copy(/homepages/32/d457207243/htdocs/app457207248/wp-admin/includes/update-core.php) [function.copy]: failed to open stream: Permission denied in /homepages/32/d457207243/htdocs/app457207248/wp-admin/includes/class-wp-filesystem-direct.php on line 200
Could not copy files."
I'm a volunteer trying to maintain a non-profits site for them. Any suggestions for a a non-coder?
