For the first time i activated the debug mode, when i opened my website underneath the homepage all kind of errors appeared.
(check the image i added)

PHP error log: Activated
PHP errors output to file: Activated
Database debug mode: Activated

After deactivating the debug mode all errors were gone and the website was fine again.

All help is appreciated to find out what happened.

Thanks!

Those are not errors, they are the database queries and appears when you activated the Database debug mode. It is for testing purpose and should not be used in a live website.
The php errors log is located in oc-content folder, or you can find it in admin panel under tools -> Debug/Error log
