Blank page after published the site

Hello there,

I published the site and get only a blank site, no error in console.If I try open panel, it shows there is unexpected error. Things run normally in local server, include panel. Before I put my own content in, the kirby plankit can be normally deployed. I feel my setup is fine, maybe?
Sorry, I am not really a developer, just a designer want to build the own blog. And idea what can be the problem or anything I should try to figure it out.

What exactly is the unexpected error? Is debugging enabled in the config file? If not, you could temporarily do that to check if we get more information.

Hello, thanks for the tips. I get Error like this

Whoops \ Exception \ ErrorException (E_WARNING)

Cannot modify header information - headers already sent by (output started at /customers/6/9/2/

I have no idea what is this as I am no developer. But I google it found this post

it resoved by adding this line in first line of index.php.

Do you have an empty first line or whitespace at the top of your config? Then remove that (and your ob_start() setting, because that is not the solution).

if I delete line and keep the index.php like this. I get an empty page.

For me the line ob_start(); really works. Sorry, I have no more knowledge about this problem. Maybe you can explain me a bit more or just tell me where I can find more information. Thanks!

I was talking about the /site/config/config.php file which seems to be throwing the error…

More often than not, the cannot modify header information error is caused by blank space at the top of php files.

Oh, Yes. That works too. Thanks!
