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!

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.

Thank you Oliver, remove those other files and update works fine as well as the site.
