Hi gents-
Using joomla 5.4.6, and went to move the install from 4.0.20 to 4.1.4, and go the error message below. Checked for the fof library, there is one listed for Akeeba (picured), thought I might want to ask before I start willy-nilly deleting or deactivating stuff :)
Hello Bob,
the console does not properly represents all the fof libraries installed on your system. It does not even shows the one used by J2Commerce.
As the message says the library fof40 is present on your site still, at the server level.
You should have only one library present, not multiple to avoid security issues and incompatibilities.
One should remain : libraries/f0f , which is the one packaged with J2Commerce and that is one we updated for Joomla 6 compatibility of J2Commerce.
Before deleting folders, please make sure you have a backup handy :-)
If you have any further question, let us know!

Olivier- Thanks! Back up site, actually copied the folder locally in case something happened. Ran the update, went smooth. Check site, looks good. Thank you for your help. - Bob
