I would be very grateful to anyone who can help me with this issue:
1 - Cannot upload media - receive following message: "The uploaded file could not be moved to C:\Inetpub\wwwroot/wp-content/uploads."
2 - Cannot edit theme's files - receive following message: "Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\wwwroot\wp-admin\theme-editor.php:84) in C:\Inetpub\wwwroot\wp-admin\theme-editor.php on line 99"
Steps Taken and Failed To Resolve:
1 - make sure all file permissions are set to 777 and they were
2 - add a new folder to server for uploads - changed WP settings to upload to the new folder but received same error message
3 - check for whitespace in theme-editor.php - there was no errors there
4 - took the theme from the server, put it into a zip folder, uploaded it to a different server - and it worked fine.
I am working with a client who has someone that runs their server-side of things. It's not my field so I don't know much about it, but he made a change to something on the server last night and since then I have gotten this error. He is very hard to work with and is saying this is an error in my php coding when I strongly believe it is not, based on my research and the fact the same files work fine on my server.
I need a strong answer to fix this and let my client know the status. As it stands now - the website cannot have any new media added to it which is a huge issue for them of course.
Thank you in advance.
