missing message after finalizing reservation

Since the last update for Solidres i get this problemi can't solve.
After the user clicks the 'Finish' button, the site gives an empty main ( as you can see in the attached files ).
The user gets the email but no message on the site about finishing the reservation. I disabled all overrides, but it didn't helped.

Seems like something is wrong with the Languages, if i use the default english it works, i still try to find why it doesn't work with the hungarian.

Edit: After testing other languages seems like the problem is with the outdated system language, seems like i simply have to wait until the hungarian language update for joomla is up to date.

Hi,

Thank you for your update, please notify the Hungarian translation team so that they can check to see if there are any errors in their translation.

Regards,
