500 Error, please check your php script / enable display_errors in your cpanel

Hello, I found this message when im trying to acess a php file on meme.planetnetwork.cf, can you take a look?
Ive set “Show Error” to ON but still the same, Ive cleared my Cache too but theres no errors to display.

Its a Meme maker script…

Some (administrator hostile) scripts manually force errors to be hidden. If so, you’ll need to dive into the script configuration or source code for errors to be enabled.
