posts dont show in forum

Hi,

during the course of today, post of mine aren't showing up in the forms even though they appear in the recent posts block and in the user profile. the post title is:

[update] install procedure for 2.3 nightly w/ preinstall.php from patched 2.2.5

After previewing and/or sending the post, various borwsers (firefox 2.0.15, safari 3) just got blank pages in response. i removed double posts. lets hope this gets through ;)

cheers,
Gue
