PDF Stylesheet - Not saving

[Rilwan Ahmed]

As the "Export to PDF" is not exporting the colors in "Status" macro, I tried adding few lines into General Configuration -> PDF stylesheet. While saving the page, I am getting below error. 

Page: <ServerName> /admin/flyingpdf/editpdfstyleconfig.action

CSS lines trying to be added:

.aui-lozenge-complete{
background-color: blue;    
opacity: 0.5;
}  

.aui-lozenge-success{
background-color: green;    
opacity: 0.5; }  

.aui-lozenge-error{
background-color: red;    
opacity: 0.5;
}  

.aui-lozenge-current{
background-color: yellow;    
opacity: 0.5;
}

Error While saving page:

I am not sure why it is not saving for you, I saved your CSS on my test instance so it's nothing in the content:

Please let me know:

• What version of Confluence are you running?
• What is the full stack trace, starting with the date stamp, in the atlassian.confluence.log when the error appears in the browser? 

The atlassian.confluence.log is in the <confluence_home>/logs directory. (The <confluence_home> directory is the path defined in the following file: <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties)
