[Bug] I've noticted a bug when I favorite stuff. The Second page is not showing my recent favorites instead it's showing a duplicate of page 7 of my favorites and it's saying that IM not logged in even though im am.

But then everything shows up when I hit the third page.

You need to use the corresponding template when doing bug reports/feature requests.

That said, the top three posts for me are:
post #841500 post #842428 post #903573
Does this correspond to what you are seeing? Also, did you try reloading the page?

the number of iamges that are displayed on each page is a user configurable option:

https://e621.net/user/edit "posts per page" ..Having that information would probably be helpful

For me, my faves seem fine.
