The system should check the file size before uploading.

I can not reproduce this part (see screenshot)
Can you check your upload_max_filesize in phpinfo ? maybe your post_max_size is lower than upload_max_filesize ?

@tibor.pacalat can you check ?

I was able to reproduce this error. it seems not to caused by files being large. It occurs if :

  1. A user copies a survey without checking the “ Copy survey resource files and adapt links “ box.
  2. If a user deletes the attached files in the resources and does not remove them from attachments.

Maybe the error message can be “There are errors with this template’s attachments. They do not exist/referenced path is incorrect.”

and we can proceed to close this issue.
