I am facing a strange phenomenon with a single website of mine. On all other websites running on the same ss version, I don`t have this problem. The only difference is, that this site also uses translatables, maybe that's a problem. However, this is what happens:

I have added five fields in the forms tab, everything was working fine. When I add the sixth field (no matter what type) it throws up an arraylist and the following error:

ERROR [User Warning]: Couldn't set response type to 403 because of output on line 130 of /mnt/weba/b2/48/53815948/htdocs/silverstripe/framework/control/Director.php IN POST /admin/pages/edit/EditForm?locale=de_DE Line 262 in /mnt/weba/b2/48/53815948/htdocs/silverstripe/framework/control/HTTPResponse.php Source ====== 253: header("$header: $value", true, $this->statusCode); 254: } 255: } else { 256: // It's critical that these status codes are sent; we need to report a failure if not. 257: if($this->statusCode >= 300) { 258: user_error( 259: "Couldn't set response type to $this->statusCode because " . 260: "of output on line $line of $file", 261: E_USER_WARNING * 262: ); 263: } 264: } 265: 266: // Only show error pages or generic "friendly" errors if the status code signifies 267: // an error, and the response doesn't have any body yet that might contain 268: // a more specific error description.

"nicht angemeldet" means not logged in

SS Version 3.1.4 and latest userforms

Can anybody give me a hint what the problem might be?

Greetings,

I came across a similar issue with Userforms where the Web server was configured to limit the number of HTTP Post requests.
I know you will think that 5 fields are not much but you may have to bear in mind or of the other Post requests that the CMS will generate as well.

I just copied the whole website to my server and it works fine. So you are right, it has to be some server configuration. If of interest for anybody, the server with problems is running at Strato, the good one is running at Hosteurope.

Thanks a lot for the hint.
