14999	Reject invalid theme.zip uploads	jstrebel	dd32	"When a user uploads (/wp-admin/theme-install.php) a theme.zip file from their desktop that may have an invalid folder structure WP accepts the upload. The theme does not appear in the /wp-admin/themes.php list of available themes so the user assumes it was not taken and they try the upload again and are met with a cryptic ""Folder already exists"" message.

Perhaps WP could validate the internal file/folder structure of the theme.zip and reject the upload with a clearer message such as: ""This theme does not comply with the standard WP folder structure for themes. Please see this topic <link to topic> that explains the proper standard. Note: Please alert the theme author to modify their theme.zip download to comply"""	enhancement	closed	normal	3.3	Upgrade/Install		normal	fixed	ui-feedback	ocean90 chip@…
