Breadcrumbs Mixup

[reggaebkk]

Hi,
I can't find other posts about this but I can't believe that I'm the only one with this issue.
Somehow my breadcrumbs are mixing-up categories as I'm navigating the website.
When I enter the website via the main page after clearing cache and reach a product, all seems fine, but as I'm navigating via various menus and modules, categories start to mix-up in an anarchic way.
I tried to disable menus and some modules but nothing helps, I don't know if something was hacked or if I have database issues or maybe some configuration problem between extensions...
Has somebody ever had this breadcrumbs issues?
You can check the website https://www.pailingemstones.com and by navigating between product pages that the gemstones categories start to mix-up...
Can somebody tell me what is wrong?

Ok... simple... I just needed to disable caching in the breadcrumb module.
