Change history (extension) - fatal error

[swar]

I have updated the app to 2.9 and since then, I receive an error on every change history report (extension), e.g. index.php?module=ext/track_changes/view&reports_id=1. It applies for both old reports created under the previous version and new report newly created under 2.9.

Fatal error: Uncaught Error: Class 'ComposerAutoloaderInit728cc314e309fb44d9f50a3c46d4fac9' not found in MYPATH/includes/libs/PhpSpreadsheet-master/vendor/autoload.php:7 Stack trace: #0 MYPATH/plugins/ext/modules/track_changes/actions/view.php(3): require() #1 MYPATH/index.php(20): require('MYPATH...') #2 {main} thrown in MYPATH/includes/libs/PhpSpreadsheet-master/vendor/autoload.php on line 7

Can't reproduce this issue. Make sure the folder exist in includes/libs/PhpSpreadsheet-master
and try to rewrite all files form original archive in this folder.

Thanks, solved, this was not a bug, just cached autoloader.
