All the time you can find support requests that are mainly or only based on an incorrectly installed style version.
You must always have the correct style version installed for the respective phpBB version. Even within a row.
For example, a 3.2.9 board may not have a style version installed that is for phpBB 3.2.8 .
Exception: if there are no prosilver style changes from one phpBB version to the next.
The styles must not be adapted and validated new for every phpBB version, for fun or because we are bored.
If you have adapted your style or created your own style, you will have to make the stylechanges with every new phpBB version.
