No matter where I go on the World Map to go questing and gain levels the Battle Option gets stuck. I click to battle and I either get a set of weird coding or it just freezes the whole page.
I can get items like Fairy Mushrooms and random boxes. But When I got an Egg it did the same broken code thing.

Anyone else have this problem currently?

Is this still an issue? The server was having issues earlier today with performance.

I am getting this too. Anytime I try to battle I get the code or just a freeze up. Been doing it pretty much all day today. Sometimes when the page does finally load, there are no monsters to fight and I just have to click the block to clear the battle.

Can someone provide either a screenshot of the error message or copy/paste it for me?

Here is an image of part of the massive text that shows up when the battle 'loads'

I tried re-logging into the site <I often leave my page up all the time> and I got into one battle but when I clicked to do the next battle it froze up on me again, then posted the text.

Yeah, it's happening to me, too. Same error too, right down to the line number.

I'll see if I can get a couple screenshots.

Oh, good. I thought it was just me doing something wrong.(I this is my third day but I couldn't do much yesterday due to this bug.)

I've run into this issue, too, but only when battling during raids. IDK if it's something to do with the old battle system or if switching from the fest zone to participate in a raid is what's confusing the database, but either way, after I tried to enter battle, the entire SITE refused to load on Chrome, and now I'm posting this from Firefox because for some reason it's loading just fine on this browser. Maybe "logging out" and signing back in fixed it on my end? IDK, I never saw an actual error code, but I don't think I'll be attempting any raids for the rest of the fest.
