The Apache Roller 5.2.3 release included an upgrade to the Xinha rich text editor which causes the Roller editor to fail to load (for Xinha users only). We have not yet determined the root cause of this problem so, for now, we have decided to revert the Xinha upgrade.
You can find a release candidate for Apache Roller 5.2.4 here: https://dist.apache.org/repos/dist/dev/roller/roller-5.2/v5.2.4/ Please vote to release Roller 5.2.4. Thanks, Dave
