Background: I was upgrading multiple plugins and when the upgrade (backend) screen comes up, it does take some time to load (I am guessing that WP is fetching the upgrade files). For some reason (server location amongst others) this screen can take a while to come up, but once the upgrading process starts, it usually goes quickly and smoothly.
Every now and then I have a lapse in judgement and am too eager to continue my work and start clicking away, and usually I realise this and stop. But not today :)
I clicked off too early and got stuck in maintenance mode.
Where I'm at: I fixed the maintenance mode without an issue as per (stuck in maintenance mode -- wordpress.org and plugin upgrade issue -- this site) but when I have gone back to the site, I have got no indication whether the plugins have successfully been upgraded or not.
As suggested in the second link above, I would like to run the update again but now all plugins are reported as being up to date.
Question: How can I be sure the update/upgrade completed successfully? I am concerned that it hasn't. These are significant plugins, would it be safe to uninstall them and reinstall (to be sure they are the latest versions)?
note: this is not a duplicate of the unanswered question: What is a good way to test that plugin upgrades have completed properly?
