 * Hello,
 * when I try to generate the sample diagram, the image on the website is not generated.
   This is the code in the backend:
 * Now comes a diagram:
 * [plantuml]
    Alice -> Bob: Authentication Request Bob –> Alice: Authentication
   Response
 * Alice -> Bob: Another authentication Request
    Alice <– Bob: another authentication
   Response [/plantuml]
 * And now some text.
 * The image on the website gets the URL [http://www.plantuml.com/plantuml/img/0m00](http://www.plantuml.com/plantuml/img/0m00).
   That leads to an HTTP error 400.
 * Do you have any ideas what might be wrong here?

 * Hi @
 * This will work, you just need to be careful with the characters, the syntax is
   quite specific.
 * If you copy and paste the following, and make sure to paste without formatting,
   it should work for you;
 *     ```
       [plantuml]
       Alice -> Bob: Authentication Request
       Bob --> Alice: Authentication Response
   
       Alice -> Bob: Another authentication Request
       Alice <-- Bob: another authentication Response
       [/plantuml]
       ```
   
 * This exact extract is used for the page [here](http://toddhalfpenny.com/plantuml-renderer-plugin-demo/).
 * Please let me know how you get on.

 * Thanks for the info!
 * I got it working now. Interestingly, the following way “A” works, while “B” does
   not (I put this into the post in Text Mode):
 * A:
 * [plantuml]
    Alice -> Bob: Authentication Request Bob –> Alice: Authentication
   Response
 * Alice -> Bob: Another authentication Request
    Alice <– Bob: another authentication
   Response [/plantuml]
 * B:
 * [plantuml]
    Alice -> Bob: Authentication Request Bob –> Alice: Authentication
   Response
 * Alice -> Bob: Another authentication Request
    Alice <– Bob: another authentication
   Response [/plantuml]
 * Method “A” is working for me for now. Thanks.
 * Out of interest: Should method “B” also work from your point of view? If so, 
   maybe this is related to another plugin that is running in my installation.

 * Ah, I just realised that “A” in “Visual” mode is exactly what is written in “
   B” 😉 So the example seems to be meant to be used in “visual” mode. Sorry for
   this confusion.
