Has anyone ever seen an issue like this before?")* Hi, I tried with Chrome and I couldn't reproduce the issue on your website. However, I was able to reproduce it with Edge. I found two things: - It only happens the first time you click on the add to cart button. Further clicks on it don't produce the issue, unless you refresh the page - while looking at the network tab of the browser, the issue only happens when an extra "prefetch" is done: [ i.imgur.com/2wjR5JX.png](https://i.imgur.com/2wjR5JX.png) When it works fine, this prefetch doesn't happen. However, I don't understand why the browser would run this prefetch. From what I understand, a prefetch can happen when there is a prefetch attribute to the tag: [ developer.mozilla.org/en-US/docs/Web/HTM...ributes/rel/prefetch](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel/prefetch) This is not the case here. Since no one else reported the issue, it might be something specific to your website. First thing would be to temporarily switch to the default Joomla template and see if you still have the issue with it. If yes, then it might be some javascript from the template messing with these. Another thing you can try is to switch the "Action button" setting of the HikaShop configuration. Using a button HTML element instead of a normal link might help circumvent the problem.
