Since DreamHost updated WordPress to 4.5.3, I have been unable to update plugins and the uDesign theme. Each time I try and update, I get this error:
An error occurred while updating UpdraftPlus - Backup/Restore: Download failed. Failed to write request to temporary file.
Here's what I've done so far without luck:
1. I've double check that all plugins I'm using are compatible
2. I've cleared browser and DNS cache
3. I've disabled all the plugins and tried to update them one at a time with the other plugin disabled
4. I have tried to find the temporary file via ftp with no luck.
At this point, I have ran out of ideas. It seems this problem started with the mail server started having issues.
I do manage other sites and I use the same plugins and I'm able to update without an issue.
Can you help
