last friday I get this fatal error on our site. We don't know how this error was triggered because it came spontaneous.
Our watchful system alerted us that the site was down.
So we looked at the site and we saw this error:
Fatal error: Class 'FOF30\Container\Container' not found in /....../...../....../domain.com/plugins/system/admintools/util/exceptionshandler.php on line 229
We fixed the issue to clear the cache and the Varnish cache.
Do you have any idea how we get this error and how we can prevent this for the future?
Kind regards,
Lumiga
