Yes it happens the same to me:
First I send some data to one of my website forms (i.e. https://opistobranquis.info/en/vimar/contacte/), I can check it stored in the admin page, so the data is in the feedback database.
Then I go to the GDPR Request Personal Data form (https://opistobranquis.info/en/home/privacitat/gdpr-request-personal-data/) where I use the shortcode [REQ_CRED_FORM]
for the Data Request form, and it perfectly sends the email both to the user and the Data Protection Officer with the link to check for the data.
When the DPO clicks the link, it perfectly shows all the feedback data to be managed. However, the link for the user who requests to selfmanage his/her own data shows a black screen, where the code is, basically, this:
<body>
<div class="gdpr-container">
<div id="gdpr-message-updated-entry" class="js-update-message"></div>
</div>
</body>
So no code (and no information) is posted for the user to self-manage.
I recall seeing this working in the past, but it is NOT working now.
Any ideas? Thank you in advance !
