Anyone else having this problem?

Which tags are you trying?

A just ruler amongst tyrants

I forgot about this thread. I honestly don't remember.

I know I saw a manga that had 2 tags on it that I wanted to see if there were any more with those tags. Except when I used those tags in the advance search, not even that original title came up.

Dumb question, but did you put each tag on its own line?

Also if they have apostrophes in them, those sometimes don't work and you have to change them slightly in the URL. Or at least I do, I have no idea if that's a site-wide issue or just me lol.

Tags with apostrophes are a site-wide issue right now

Should work now.
