Craziest thing just happen.
I was updating a component on my test site and I got a fatal error with the below description.
' Fatal error: Class Joomla\Input\Input contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Serializable::3 , Serializable::1 ) in C:\...\libraries\vendor\joomla\input\src\Input.php on line 41'
I check the local history for that file and nothing has changed. I also tried making it abstract and that caused the next fatal error.
'Fatal error: Class Joomla\CMS\Input\Input contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Serializable::3 , Serializable::1 ) in C:\...\libraries\src\Input\Input.php on line 31'
Anyone seen this?
