When we log in from the front end (J4) to create an article we get the following error IF we enter the current date in the Start Publishing date field:
Call to a member function format() on bool
If we leave the Start Publishing date field empty the article saves and inserts its own incorrect date:
2010-09-12 09:02:27
• If I then log in thru the Joomla Administrator and inspect the Article publish date it has the correct current date.
• If I switch to the J4 Cassiopia template, the issue goes away and date reads: 04-19-2022.
• Switching language file between US and British English doesnt have any effect either.
Using:
• Helix Ultimate 2.0.7
• Joomla 4.1.2
• PHP 7.4.29
