HTTP Status 500 - Cannot call sendError() after the response has been committed

[Rich Webb]

I'm doing a new setup on CentOS 6.9 Final - used the .bin installer.  Right after I associated my server ID and pasted my license into the box this message comes up and errors out.  I selected the evaluation using the internal DB.

This is a fresh install of CentOS as well as a clean install of Confluence.

[g]

Can you test the issue with a new evaluation license? Are you using already used production license?

Stop confluence (or kill the process) remove or rename <confluence-home> directory and start Confluence.

That will trigger setup process again, this time use evaluation license and let us know how it went.

If it fails again, we would need a full log (atlassian-confluence.log) to see what and when went wrong.

Cheers!

That may be the issue - I think I chose eval but then put in my production license at a later point because I read somewhere that I could move my license to another server later on.    

What I'm attempting to do is I want to install it for testing on my new virtual machine (fresh install) and get familiar with the product and then do a clean install on my VPS.  My test box has an external MySQL database server available but I couldn't figure out how to get back to the question in the setup where it asked me eval or production.  Can you help me just reset the install completely?  I did do an uninstall and remove the directory it was installed in but then it seemed to have somehow remembered my selection of "eval".

In that case, remove the <confluence-home> directory and the setup process will start from scratch afther restart.

p.s. You can find the location of the <confluence-home> if you look into <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties file

I did finally get it up and running - I ended up using my production key though.  Is there a process when I'm ready to move it to the production box to tie the license to the new server ID?  Or does the server ID matter?

Rich

[g]

The license is not tied to the Server id - What is server id. But only one instance can be active with one license.

Please note that all owners of a comercial license are entitled to a free developers license which is perfect for testings and upgrades.
