I have found the solution for the issues in my Nextclous instance. The solution comes froma topic from Akhenaton in July 2016 (Failed integrity check after manual upgrade - #6 by Akhenaton)
- Add the folling line in the /config/config.php file:
→ ‘integrity.check.disabled’ => true, - Now reload the page ‘Security & setup warnings’
- When you see the yellow banner click on rescan
- Log-out
- Log back in as admin you will not the integrity failure anymore
- Now delete the line that you put in your /config/config.php file to re-enable the integrity check
This did work for me. And I hope someone finds use in the topic…
Regards and stay safe.
