WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Missing a temporary folder., by stmux I finally figured out what the problem was. The hint was that php defines the temp folder. I found that on the Windows installation php is defaulting to C:\windows\temp. Then I checked the user permissions and NO permissions were set for that folder. Setting the permissions resolved the issue. Thank you again for steering me in the right direction. jay Reply To: Missing a temporary folder.
