Yes   PayPal  Commerce latest version that works good with cart version 1.3.3   is indeed  v1.0.0

please check that you have the correct version of the Mercato for your AbanteCart v. 
If using AbanteCart v 1.3.3  (the latest)  then the Mercato  should be v 1.2.4   and I see that it had a update to the Mercato today  5/29

Hello,  Can we still use PayPal Pro in 1.3.3,   there is no version in a clean install.  But an upgraded version still has it.  One of my clients has PayPal Pro for all it's features  -  need to know if it will continue to be updated in future versions of AbanteCart.

What cart version are you using?
You can see your version in the footer of your admin page

There are some patch files for some versions.

Unknown currently.  they indicate they are 18% complete.  So best guess it will be awhile.

Hi, I navigated around your site,  changing categories,  changing display from grid to list,  all worked correctly.

Suggest you try clearing your system cache in admin,   and also your PC browser using cntl+f5
often times when doing lots of changes in your site, you need to remember to clear your cache.   AbanteCart has a robust caching system to speedup the delivery, works great on the customer end.  But can fail to update when admin is making lots of changes..
