twitter bootstrap - Prestashop slider settings won't update -

so i've done fresh install of prestashop.

version: 1.6.0.9

theme: prestashop default bootstrap theme

i'm trying make default slider full width.

to this, followed mini tutorial says have un-hook theme configurator in module position section leaving slider , go slider settings , change max-width 1170px.

however, every time change of values, max-width, speed or pause , press save, doesn't save?

it reverts original default values though states "the settings have been updated."

anyone know why values aren't changing?

try editing tpl file of slider. first close div tag @ top of tpl file , again open closed divs @ end.
