Do you know what PHP version you have? Likely your PHP version is too low.

It seems we're using a file settings server before the autoloader is loaded.

я несколько раз скачивал из github, официального сайта, и устанавливал matomo. Проблема не решилась

I suppose you downloaded the 4.x-dev branch from Github which requires PHP 7.2+. Maybe you could try the 3.x-dev branch?
We are currently working on the 4.0 release but 3.X is the latest available

скачивал ещё с официального сайта matomo, а там минимальные требования PHP версия 5.5.9 или выше, а у меня выше

@Retrafic could you edit the file core/testMinimumPhpVersion.php and change around line 87 the code to this and then see what happens?

Basically you remove a few lines and replace them with return true;

Спасибо большое! получилось установить. проблема была с версией php. Поднял до PHP 7.3 и всё заработало

Thanks a lot for letting us know @Retrafic I'll reopen the issue anyway as it looks like there is some issue which many people might run into with Matomo 4.
