I have this issue with my Virtuemart shop when a user tries to Register their account.
The about the used version:
Joomla: 3.9.3
Virtuemart 3.4.2
Template is from virtuemarttemplates.com

Settings:
Cache: off
Gzip: off
HTTPS: on
Plug-in: Pagecache: off

I don't know how i can fix this problem. Please help me out

You can get better information about the error using this plugin:  https://www.joomunited.com/products/token-interceptor

Or turn on Joomla debug.

Thank you for your replay. I forgot to mention i allready installed this plugin.
Unfortunately, the problem still exists.

I will check the Joomla Debug. I've send the hosting to check if they don't use any sort of chache.

.htaccess settings wrong ? www vs non www ?

Using https ? Is https for sensitive area on in VM configuration ?

I tried the https://www.url vs the https:/url and unfortunately there was no change.

Is https for sensitive area on in VM configuration ?
Yes it is.

I also disabled the SEF and URL rewrite.
I made a new menu button on the language option: all
Also no change...

The strange thing is that it's only happing on a mobile registration.

This is the code i get while trying to save the user:

This morning the hosting company moved the website to on other server and the problem disappeared.
