Hello Britt,

yes, I answered Patrick directly.

There is nothing wrong with the J2Commerce install, there is just some cleanup to be done on your server... Coming into Joomla 6, we did not want people to carry obsolete and unsupported versions of the FOF library. You should just continue to have our version of the library, which supports Joomla 6. Other versions do not and are 'dead' code that should not linger on your site (one obvious reason: security).

The installer message tells you that there is f0f40 in your /libraries folder and that needs to be removed.

Ideally, you can do so in the Joomla console (Manage Extensions -> filter by libraries). If it is not visible, or if you removed it and the warning message still shows, this will need to be removed from the server. Just remove that /fof40 folder manually. You need to keep the /fof folder.
