Today, I have been struggling to fix one of my client’s website build on WordPress site.
The problem was simple, blank screen.
When I googled about the problem, I found out many solutions such as
- Turn on error wp_debug to TRUE and try to fix any syntax error or any PHP related error
I did it and the problem I found the error as below:
Uncaught exception ‘InvalidArgumentException’ with message ‘Identifier “system” is not defined.’
