Hi @IOPNdev,
I think you’re on the right track with SELinux; unfortunately I haven’t used that toolset myself but if you want a quick way to test you can always write a quick .php script to check writability:
<?php
echo is_writable('/var/www/uploads/scheduledTaskLogs/Usagestatisticsfileloadertask-5ebe386638cfe-20200515.log')?"Writable\n":"Not writable\n";
Don’t forget that this will need to run in the same context as OJS, i.e. via the user account with the cron job if using cron, or with the same credentials as the web server if using the Acron plugin.
I believe Counter stats depend on the same toolset, so fixing this may resolve the Counter issue.
