File Uploads / Attachements not working

Hi there,

I am having trouble with the file uploads / attachments on this form.

Here is my contact-form code:

<div class=”column one”><span>Foto (JPG, PNG oder GIF mit max. 6 MB)</span>[file foto limit:6mb id:foto class:foto]</div>
<div class=”column one”><span>Lebenslauf (PDF oder DOC mit max. 4 MB)</span>[file lebenslauf limit:4mb id:lebenslauf class:lebenslauf]</div>
<div class=”column one”><span>Immatrikulationsbescheinigung (falls vorhanden) (PDF oder DOC mit max. 4 MB)</span>[file immatrikulation limit:4mb id:imatrikulation class:imatrikulation]</div>
<div class=”column one”><span>Zeugnis #1 (PDF oder DOC mit max. 4 MB)</span>[file zeugnis1 limit:4mb id:zeugnis-1 class:zeugnis-1]</div>
<div class=”column one”><span>Zeugnis #2 (PDF oder DOC mit max. 4 MB)</span>[file zeugnis2 limit:4mb id:zeugnis-2 class:zeugnis-2]</div>

and here the corresponding code in the e-mail:

Anhänge:
[foto] [lebenslauf] [immatrikulation] [zeugnis1] [zeugnis2]

I´ve followed alle instructions from https://contactform7.com/file-uploading-and-attachment/

Tested a custom folder as stated:
define( ‘WPCF7_UPLOADS_TMP_DIR’, ‘/your/file/path’ );
but that didn´t work either.

Could you please helpe me out.

Many thanks and best regards,

Daniel
