internal 500 error in php pages "Resolved"...

[willamsphp]

I'm having the following problem.
When I opened my site with html pages the Vesta operates normally

example: http://ksystem.com.br "no error"

more when trying to open any page that is not in php open of the error 500

example: https://ksystem.com.br/financeiro/index.php "with error"

Another thing I noticed and that this problem only happens with some php files with others does not happen this error

example: http://perfuratriz.ml "no error"

example: http://leia.tk/index.php "no error"

example: http: // http://leia.tk/galeria/index.php "with error"

Check error log, is probably an error in your script.
