I had this topic made the other day with some of my content:
https://www.aaroads.com/forum/index.php?topic=8909.0
I wanted to double post (it was a few days since the first post) with some more content, but everytime I try it redirects me to a white page, and if I try to refresh it, it redirects me to a new topic page saying I forgot the title and content of the post.
I think it's because you had jumbo sized images in the first post. We had somebody else with the same problems before. (EDIT: See this thread (https://www.aaroads.com/forum/index.php?topic=7920.0).)
If you can make a thumbnail images that links to the bigger ones, that might fix the problem.
As far as I can tell, this is a bug in SMF, and not on our end.
Oh, ok. Thanks for the help.
