In JA Onepage after upgrading to Extensions Manager 2.6.4, I can no longer access the Extensions Manager.
orsomannaro Hi,
There maybe something wrong with the upgrade, I've installed this version for you and it works fine now.
Kindly check.
Thank you saguaros.
I have to upgrade another instance of the site: how do you suggest me to proceed?

You mean upgrade in another website? You can download the latest version and install into that site, it will be fine.
