Image slider dissappeared blank

[limonaderose]

Hi,

 

I run a boutique on presta v 1.6.0.8.

 

Yesterday I upgrade homeslider to v.1.4.5 and it worked, but later on the day, i notice there is no more slider on my homepage. There is a blank soace instead of it. I was not modifying anything related to that in the back office.

--> I did'nt changed hook

-->When I run live edit, I see the presence of the hook for the slider, but the slidder is no appearing

-->The slider is enable and parameters are set correctly

 

I uninstalled the module and replace it with a old version from a backup. The slider is not coming back. So I understand the problem does not come from the module update. Cleared cache from navigator and shop.

 

I also run a test boutique on local host, and the slider dissappered too this morning, as I was installing a social share button.

 

Anyone knows what could be causing that?

I now knoe that the problem appeared when I cleared cache.

 

Why does clering cache would have such effect?

So I found the problem: I had modified header.tpl (many days ago without clearing) and after clearing cache, it was searching for an undefined index which stop the script and prevent the slider to show up.

Solve by adding an if condition somewhere.
