My client uses Freeform Pro to take resumés and cover letters through a lengthy career registration page. After working fine for two months, applicants started getting this error:
The form you submitted contains the following errors
- The file could not be written to disk.
They only have about 10 megs of files in the upload folder, and have collected 274 documents already through this Freeform Pro form. I was able to upload files through FTP to the upload destination, so it doesn't seem to be a server limit. They are using EE 2.6.1 and Freeform Pro 4.1.3
Is there limit in ExpressionEngine, Freeform Pro, or the server that can be changed to allow uploads to continue? What might be causing this?
Edit: After further investigation, I found the problem appeared only for logged out users. If I was logged in, I had no problem uploading files through the form. This indicated the problem was not a hidden limit setting.
