Getting error on update
Installation blocked: the following FOF library directories were found alongside the F0F library used by J2Store: fof30, fof40. Multiple FOF installations in the same Joomla instance cause class-loading conflicts. Please uninstall those libraries before installing J2Commerce. Check the libraries. If no library is present, you may have to delete the folder(s) manually. Error installing component No idea what to do, when i disable these still get same message. Akeeba says not to remove. So what do we need to do?? Thanks as always!#838 Cannot update to latest version due to Fof?

Hello Abraham,
the installer told you you have mutliple instances of the library f0f on your site. You need only one.
Akeeba does not use the library f0f in Joomla 4 and over. You still see Akeeba's name because it was created by Akeeba.
The one library to keep is
revAC17961 from 2024-04-12.
It looks like the list of the libraries found in the Joomla console is not representative to what is on your server.
Make sure you backup your site, then just keep libraries/f0f.
Olivier.
