Error With Showing All Categories

[doarbiz20]

Hi there,

 

I purchased template for my website which sells various products under various categories.

I created a page that shows all categories to choose from leading customers on the a page showing all the items

of the category they clicked on.

 

But there's a problem on the page showing all categories. First let me clarify that I installed my prestashop website on Linux

and I am using git. The problem is this error:/var/www/mywebsite/releases/20160424113159/cache/smarty/compile/91/ce/6a/91ce6a9409af6e38c7876a53905ec49989ccd8e6.file.category-count.tpl.php on line 28

Notice: Trying to get property of non-object in /var/www/mywebsite/releases/20160424113159/cache/smarty/compile/91/ce/6a/91ce6a9409af6e38c7876a53905ec49989ccd8e6.file.category-count.tpl.php on line 28

 

Now I don't see that the error actually takes any effect on the website but its just displayed on the page but I don't

see any glitches or problems with the website or its script. It's like the error is just on a page that is causing any problems to the page itself but here it is

I guess you cleared cache already? It might just be an error from the dev version

How do I clear the cache?
