Hello Auge

I'll answer myself

I will adapt the installation and update instructions

No need to change the installation instructions because it promts to upload the whole folder (including the file config/VERSION. There's also no need to change the update instructions because the necessarity to upload config/VERSION is always stated there in step 1.

- above version 2.3.7: Load the files update/update_2.3.5_2.4.php, config/VERSION and update/update.sql up to the server.

and change the error message to be more descriptive.

This task remains.

Tschö, Auge
