Last night I upgraded WP to 3.9.1 and last version of JetPack.
Suddenly, my two sliders went out. Images were gone from Weptile.
Tonight I deleted both widgets and created a new one, with responsive disabled, to a size of 210x210.
It continues showing 210x320, like the last adjustments I made to the deleted sliders.
Could you tell what must I do to make this work correctly again?
