I'm having a little bit of trouble,
I'm currently still using beta 13, can anyone help me upgrade to 15 please?
It would be helpful if you described at which point you struggle.
JAC Happy to do so over at metabullet.com if you'd like to ?
Looking at other posts from OP. I think it's a composer memory issue.
MODS - please mark as resolved. See https://metabullet.com/d/15-updating-flarum-from-beta-13-to-15
