Fix Upload Failed to Write to Disk Error in WordPress

First, connect to your WordPress site using a FTP client.
For this tutorial, I am using the free FileZilla FTP client. If you are using some other FTP client, then it might look a little different.

Check your ‘Upload’ folder permission

Once you are connected, you need to right click on the wp-content folder and select file permissions. Normally, this folder should have 755 permission, and if this is not the case, then change it to 755 right now. This is because WordPress needs access to write files in your wp-content/uploads directory to enable certain functions, and if this permission is not set correctly, then you will not be able upload media to your WordPress site.

You also need to make sure that file permissions for individual files in your wp-content folder are correct.Once again, right click on wp-content folder and select file permissions. This time we will change permissions for files.
Enter 644 in the numeric value and then check the box next to ‘Recurse into sub-directories’.
Lastly, you need to click on ‘Apply to files only’ option.

Click on the OK button to continue. Your FTP client will now set file permissions to 644 for all files in wp-content folder.

You can now open your WordPress site and retry uploading files.

Exceeding your storage quota

It’s a bit strange but users can get this error if they are exceeding their storage quota. Users on webhosts with shared hosting plans get packages with very low storage space, such as 500MB, 1GB, 2GB. If you are the one who is hosting multiple WordPress sites and upload lots of pictures then chances are that even 1GB storage will soon become full. If the storage quota is exceeding, then your web host won’t allow you to upload any other files, and this error occurs.

To check your allocated space, Login to your cPanel and check the left sidebar. Notice the “Disk space usage” field, which will inform you how much disk space you are using, and your total space as per your hosting plan. If you are exceeding then it’s time to upgrade to a better plan, or delete files in your account that you do not require.

Clear temporary folder of the server

Sometimes this issue occurs if the temporary directory where PHP stores the newly uploaded file is full or is poorly configured. This temporary folder is located on your server and in most cases you cannot access it using FTP. You will need to contact your web host and ask them to empty it for you.
