attachment upload thumbnail link problem

[forums55]

I'm able to upload attachments in a thread and place them in the post with [ATTACH=CONFIG]"number"[/ATTACH].

They are showing in thumbnail in the post but when I click on them to enlarge the link is broken. The problem of the link is an extra !m!

e.g. http://www.sitename.com/!m!attachment.php?attachmentid=45&d=1410972752

if I remove that !m! the link works just fine showing the full image. How do I fix this so that the upload links are proper?

Thanks.

today, 1 day after the posts, the links work just fine and the "!m!" have dissapeared from the links.

i'm totally confused.

I'm using cloudflare I dont know if that could be the problem, because of its caching function?
