 * Since upgrading to php8 I got the following Error after registration of a new
   user:
 *     ```wp-block-code
       PHP Fatal error:  Uncaught ValueError: Unknown format specifier "S" in /var/www/myproject/wp-content/plugins/profile-builder/front-end/class-formbuilder.php:362
       ```
   
 * After some research, I found out, it is some php8 related problem. Could you 
   fix this soon and update the plugin to be compatible to php8?

 * Hi [@dosimo](https://wordpress.org/support/users/dosimo/),
 * This fatal error is caused by a wrong translation. Could you please let me know
   what language do you use on your website?

 * Hi [@dosimo](https://wordpress.org/support/users/dosimo/),
 * Can you please check if you have modified the following string “The account %
   1s has been successfully created!” ?
 * _NOTE:_ _Above you see the following: **%1s **make sure that in your translation
   for german, this will be exactly like that (it will stay the same), lowercase,
   the number existing, and the percent sign ( **%1s **)._

 * I haven’t modified anything. could it solve the problem, by updating the translation-
   files in wordpress?

 * Hi [@dosimo](https://wordpress.org/support/users/dosimo/),
 * To fix this issue, you can use a plugin like Loco Translate to search for the
   following Profile Builder string: “The account %1s has been successfully created!”.
   Please search for it and check if the string has **%1s** in german translation.
   Let me know how this goes.
 * We have checked our files, and the string is write correctly.

 * I have checked the translation files and there were _**%1**_S instead of _**%
   1s**_
 * But after correcting it, the error still persists. Maybe this is not the problem?

 * Hi [@dosimo](https://wordpress.org/support/users/dosimo/),
 * That’s the issue the %1s needs to be written with lowercase (s). Make sure you
   are editing the right locale of your language. I remember Deutsch has a formal
   variant as well, maybe you edited one but use the other? Does the error remain
   the same after you make this change or perhaps it’s similar but changes a bit?

 * Oh, thank for this hint. It worked now.
 * But I did not make any changes to the files myself. They were automatically synchronized
   by WordPress.
