With JQuery UI Tabs v.3 there isn’t an option to make the tabs bookmarkable. In other words when you click on the tabs the URL does not change therefore you can’t link or bookmark anything other than the default tab.
Here is how I solved the problem… [UPDATED!]
This is one miserable problem with a very simple solution. It has to do with multiple python interpreters in mod_python v.3.2.8 and multiple virtual hosts. To remedy the situation, add the following line inside your <VirtualHost> declaration in your apache conf file:
PythonInterpreter main_interpreter
Restart server and all will be better. For more info see trac ticket #3455
UPDATE: All is not well in the world of mod_python and trac. The above solution does improve matters but there are still issues. Many are suggesting to use mod_wsgi with trac to manage multiple sites on virtual hosts. Is this the beginning of the end of mod_python?
