We have migrated the Forum to another server and have been facing a weird problem since then.
Any Forum topic having more than 18 replies opens a blank page. Topics having less than 18 replies are showing fine.
Even when we try to manually update some topics, when we cross the figure of 18 the page becomes blank.
Please suggest what needs to be done, this is a live forum and many posts are not visible since past 4 days.
