Why this is happening? I have specified a custom path for file uploads but sometimes when customer fills out the form, uploads images and submits the file paths are all jibberish and uploaded to bricksforge temp folder instead?
Which actions are you using for your form?
Create Submission, Webhook, Redirect and Email. This is not happening all the time, but has happened twice now when client has submitted a form. And the submission entry for the file upload filed lookes like this, instead of a normal url address -
{“file”:“/home/mydomain.com/public_html/wp-content/uploads/bricksforge/tmp/image.jpg”,“url”:“https://mydomain.com/wp-content/uploads/bricksforge/tmp/image.jpg",“type”:“image/jpeg”,“originalFilename”:“image.jpg”,"originalFilesize”:2586303},
Thanks! 
Can you reliably reproduce when it happens that the images are uploaded to the temporary directory? 
Edit: I just tried it with a slow internet as hitting the submit button when files are still uploading, and this time no file url’s were included to the submission, it was empty. Any way to disable submit button when files are still uploading?
I also can see the these files were uploaded to the bricksforge tmp folder, in my server, although not included in the submission just a blank field.
Original: I can not unfortunately, every time i use the form it works fine, and most of the time when clients use the form it works fine also… just had two occasions so far when this happened. I’ll try some more and keep my eye open. Though maybe something to do with submitting the form when file still uploading or something similar? Trying to avoid it.
