Possible causes that can led to ‘failed to write file to disk error’
The possible reason that can result in uploading errors can be incorrect folder permissions. The permissions that you assign to a folder make it possible to access and perform read/write operations. But if you set incorrect folder permissions in WordPress it stops you from uploading and stops the write operations as well. You are no longer able to write or add files to a specific folder. Whenever you try to do so the given error messages will be displayed :
- WordPress failed to write to disk.
- WordPress has failed to upload due to an error.
- Unable to create directory wp-content/uploads/xxxx/xxxx.

Change Folder permissions
- Simply use an FTP client to get connected to your website. You can use FileZilla for this purpose.
- After getting connected, right-click on the wp-content folder and click on permissions.
- A file permission dialog box will get displayed, where you can set the file permissions for the owner, group, and public. Just enter ‘755’ into the numeric value field.
- Also, check on the box ‘Recurse into subdirectories’ and select the radio button option ‘Apply to directories only’. Then simply click on ‘Ok’.
- Now you have set the permissions ‘755’ to Wp-content and all of its subfolders.
- You also need to check the individual file permissions of the files in the Wp-content folder.
Change File permissions
- Now we will change the file permissions for all the files.
- Right-click on the Wp-content folder and click on permissions similar to the second step.
- In the file permission dialogue box, this time you have to enter the numeric value ‘644’ and check on the box ‘Recurse into subdirectories.
- Now simply select the radio button ‘Apply to files only’ and then click on ‘Ok’. The permissions for all the files in the Wp-content folder have been set to 644.
