Hi!

Anyone know what happened with this?
my post list seem very bad..

https://www.dropbox.com/s/fwk27yhxhl8o13d/IMG_20150914_120949.JPG?dl=0

days ago all is fine, after few hours customizing and playin ..the post list turned into a mess without I'm knowing the cause, the appearance of the desktop and the editor is normal, only in the position of mobile screens there seems to be the size that does not fit, I've tried to look and play around with CSS on layout "upost-" but increasingly unclear, and now I'm missing the '+' icon for read more.

how to restore the original condition? I've tried reinstalling the theme and all the files in it, but to no avail...

I just need back to vanilla mode on the post list css and other things related, support access is granted.

Thank you!
