Where is my error log hosting?

I do not understand your question.

When I put what you tell me to activate the error log the page goes blank, but if I leave it as before the error 500, It’s a directory and it does not work Other directories they work

I mean why would the URL you posted work?

Surely you need search.php?action=search2 or index.php to be in the URL first?

I made a modification to the url and already all urls do not need index.php, but I still put index.php live still not working

Are you logged in when trying to search?

yes


@Madirex Above url loads fine.
http://foro.circuitsbm.com/?action=search2

…yes, solved!..
