Using Drupal 7 and Siteground hosting, when I try to upload images at registration I get this error, but randomly.
An unrecoverable error occurred. The uploaded file likely exceeded the maximum file size (128 MB) that this server supports.
The form has 2 image fields, a multiple upload and the standard user image field. Sometimes it works, sometimes doesn't work with both fields.
What could be wrong, hosting issue or module issue?
