No excerpt in my grids part 2

Hi,

I don't see a button where I can signup! Can't reply to the topics. That's why I write a new question.

Excerpt is enabled for all grids, but not showing at all (almost 17000 posts).
I stripped all html from one post and put some text in there.
From this particular post the excerpt is showing. Hooray.
This means that html is causing the problem. But I don't know how to fix that.
Probably some adjusting coding in your post grid plugin?
Unfortunately I can't do it without html in my posts.

NB. I used the grid plugin one year before, and html was never a problem in my posts.

Thanks in advance,

Paul
