How to reset positions and appearance of default template

[Summit]

Hi,

I use prestashop 1.6.0.8.

In the modules > "position" settings I just deleted by mistake all modules.

Now the whole appearance of the shop is wasted and I'm pretty angry with myself.

Is there a way to reset the bootstrap-default-template.

I cannot just delete the shop and set it up fresh, because I worked hard to get over 6000 products into it:(

cheers,

Summit
