I have a weird behavior i can't explain on my forum. After the upgrade to 1.0.4 i noticed that one thread was no more accessible, i get an error message each time when i click on it.
What is even more weird is that after some testing it appears that it is the content of the post itself which make the thread to crash, i mean each thread i will open with this content will crash.
On the other hand it seems that the legacy html tag fix altered a little this particular post, if you have 1.0.4 version try to post a thread with the following content and tell me if it crash for you too :
