[SOLVED] "Add to cart" missing

Hello there

I was working on my store this evening and I figured out, that I cannot add the articles to cart: There is no button anymore. Since I manipulate the view that for some articles, this button is not present, I rollbacked all custom changes on the view, but there is no effect.

Products, I'm sure, I was able to add to the cart, I'm unable now to add to cart and I have no idea where to start looking.

What I did in the last time: Update to 1.6.0, tried to update the Views (rollback my changes and add them to the new views -> but like i said -> rollbacked everything), give the product anyway dimensions, add new prices, update the language files via settings.

I'm pretty sure, it's something I do wrong, but what

I would appreciate a hint where to start with my search coz I have no idea
Thanks and regards
Mike

Okay, I did this and it works now!
Sorry, I didn't found that option: I only checked for the "Shop as Catalog only"-Option.

Now, I will add the code again to the views and try again.
Thanks

So, this must be a BUG? As all was fine before upgrade for me.. I could not sleep all night thinking Akeeba or another template messed something up.
