Flushing the cache

So I went to make a post in the Champagne thread ( Which Champagne are you drinking? - #12242 by P_a_u_l_Christensen ) and after I entered the CT link and the preview loaded I noticed a typo (“cirtus”). So I went and edited the original CT TN to correct it. I deleted the link in my draft post and re-entered it, but the typo persisted, presumably because once you have a copy of the TN in the WB cache you don’t refresh it or check to see if it has changed. I tried a Shift-Reload of the page and re-entered everything, but still the typo persisted in the preview.

So is there some way I can force flush the CT preview cache or is the typo stuck there forever?

Sorry, just seeing this.

I don’t know how CT’s window preview works, but it’s drawing from CT, as it is a preview window. Had you published it with CT’s ‘share on other sites’, like the photo below, it creates a new thread and you can edit/amend the text/photos within it

This is a question for Eric as it’s his system that generates that snippet text. I would guess that it doesn’t get updated when the TN is edited.
