Undefined index: category; when clicking on a tag

[boneless]

Hi. I'm running Prestashop v1.7.2.2. I have installed the 'Block Tags' module, which seems to be working fine. It displays correct tags on the left side of products page. However, when I click on one of the tags, I get this error:

 

ContextErrorException in smarty_internal_templatebase.php(157) : eval()'d code line 626: Notice: Undefined index: category

Please help me understand what's going on. Thanks

See if you can get rid of the category mention in catalog/listing/search.tpl

The search.tpl contains only one line of code:

{extends file='catalog/listing/product-list.tpl'}

product-list.tpl has no mention of a variable named 'category'. At the start it has a "{extends file=$layout}" and I don't understand where that $layout comes from. Maybe it has something to do with it?

Here goes 1.7...

The template hierarchy is a little chaotic. It should be extending category.tpl at some point, I believe. Probably. I honestly don't remember off the top of my head, I gave up on 1.7

Yeah, it's very confusing. I worked with Opencart before, and even tho I didn't have any experience with it, I learned after a couple of days. But with this one, I just can t wrap my head around it.

You can switch back to 1.6 or try thirty bees if 1.7 is too obnoxious for you
