Error 400 Bad Request after publishing post

[Hiwelt]

Since yesterday (the time before everything was allright) I always get an error message when I publish a new post.

The post itself is published correctly but I persume (because I am no expert) that there is something wrong with the sitemap.xml. Something like this is said in the error message.

I made a screenshot of this message which can be seen here.

I updated the following plugins to the newest version today but it did not solve the problem:

• Suchmaschinen-Sitemap Generator to version: 1.4
• Einträge via XML-RPC erstellen to version: 1.43

Although the posts are published correctly I think something is going wrong. Shoud I be worried?

Any suggestions of what to do will be appreciated.

I don't think, that one of these plugins is responsible for the error. Have you the plugin installed, that announces new posts to google and other sites? Could it be, that you have configered in this plugin wrong URLs for the announcement? I think you used a ":" insted a ";".

Hi!

Ask your provider if he installed mod_security. This can cause stuff like that.

@kleinerChemiker
First of all thank you for your hint - but there are only these both plugins installed which are announcing new posts. I have checked them and could not find somethig unusual in the settings. I have not touched them after the original installation nevertheless the error came up out of the off

@garvinhicking
I will do so and come back with the result later. Thank you for your quick answer.

Can you post the URL list from the Sitemap Generator?

[Hiwelt]

I am not quite sure if I identified the file you have in mind but I looked for the latest modified file in the s9y root directory and this was [url=hhtp://www.ahlers-web.de/misc/sitemap.xml]sitemap.xml[/url] from Jun 20 23:16, 419.2 KB (429,241 Bytes).
Was it this you meant?
Sorry but I am not an expert in this subject.

I mean the configuration line of the Sitempa Generator plugin. I think you use an ":" to seperate the URLs but you have to use ";".

Yepp, I found it now. It says at URL-Liste für Pings:
http://www.google.com/webmasters/tools/ ... ingly.com/

That's all, do you mean it should look like this instead?
http://www.google.com/webmasters/tools/ ... temap=%s[b];[/b]http://rpc.twingly.com/

This would astonishing me because it worked fine with the ":" all the time before.

URL-Liste für Pings
URLs für Pingbacks (%s wird durch URL zur Sitemap ersetzt, verschiedene Einträge werden mit ';' (Semicolon) getrennt, fall nötig muss ein Semicolon durch '%3B' ersetzt werden).

This means, you have to use ";". I don't know, if it works with other characters too.

I've changed it (":" to ";"),
I've saved it,
I've tested it (result),
it fixed it
you've made my day, many thx
