Saving extension configuration fails
This has already been reported here:
Moving the discussion to mantis to have all things in one place.
When trying to save the modified configuration of an extension, I get a message "Saving settings.." and eventually a flash message saying "Configuration was saved". Then pops up a Windows download dialogue about ajax.php.
The configuration changes were NOT saved.
The Backend log says: "Core: Error handler (BE): PHP Warning: array_pop() [<a href='function.array-pop'>function.array-pop</a>]: The argument should be an array in /.../t3lib/extjs/class.t3lib_extjs_extdirectrouter.php line 90"
