I just successfully installed 0.9.6.3-rc1. After logging into the Manager I changed various settings in Tools/Config. On saving the configuration, interesting things began to happen: An "ACCESS DENIED" message
appeared along with things that didn’t make sense. Basically, HTML that belongs to some JIRA page gets superimposed on MODx. I cleared my cookies to log out and this is the login screen now:
http://paste2.org/p/86796
Note that the actual MODx html only begins at line 178.
The log-in form does appear but due to the html chaos it doesn’t get POSTed to the right location, so log-in is impossible.
Sorry, I can’t specify any reproducable steps -- I changed a lot of the typical settings in one go before saving.
