Yes, I'm testing in my local server, I have uninstalled all the plugins that only has upgrades until 2.4 version and I'm checking the use with the upgrade with plugins until 2.5 in the upgrade until 2.6.
I have unistalled "Unittest" plugin of /admin/tool, too, why it's "missing from disk" when I upgrade from 2.2.4 to 2.6. It's correct doing the uninstall of this pluging of admin tools from 2.2.4 version to upgrade to 2.6?
When I finish of doing checkings I will write results of upgrade from 2.2.4 to 2.6 to you.
Thanks.
