I am running WordPress with Semilogic Theme and its plugins. Every thing is working fine, But I observe a very unrealistic problem.
when I use Custom "permalinks" through wp-admin->options, and set it to /%category%/%postname%-%post_id%.html
it doesn't work. Though during my testing i try different combinations, it works for some (occassionly) but next day it stop doing so. Not sure what is the problem.
I can use given options perfectly with my installation.i.e. name bases, numeric all other links are working.
