How to Fix Missing A Temporary Folder Error In WordPress
Most likely this error is caused due to the incorrect folder permission in your hosting environment. WordPress uses a temporary folder to store various files before saving them to the desired location. Whenever the folder permissions in your hosting environment are not appropriate, WordPress is not able to store your files in the temporary folder and throws the error. This is the reason why you find it difficult to upload images and files, update themes and even the WordPress core.
In my case I am running WP 4.94 on a local Windows 7 Enterprise Server. This problem began with the version prior to upgrading to 4.94. The strange thing with this problem is that the upgrade to 4.94 downloaded and installed perfectly via ftp. Updates for plugins are also downloading and installing with no problem. Why would this be isolated to only uploading images? BTW, since I am on a local connection I can use the “Add From Server” plugin to import images locally on the LAN. The problem arises when an Author tries to upload images remotely.
Thanks for your suggestions and insight,
