Hello all, I think we’re seeing two different issues here:
1) @enigmaverse (and @djforge?) is seeing that when you hover over links like the “Activate” link on the Plugins page you get a tool tip. I see this too, if they’re annoying enough it should be possible to turn these tooltips off (for firefox, and safari, but not chrome) by following the directions on either of the following pages. Please be careful, the directions at these links do involve modifying your browser’s internals and will effect ALL websites (not just WordPress). Does either of those solutions look like they might work for you @enigmaverse?

2) @gplum’s original screenshot looks like a different problem to me. Unfortunately, I can’t make it happen on my blog so I’m not sure what’s causing it. Thanks for the link and error text @gplum, the source of the problem appears to be a translation module, but I’m not sure why it’s happening for you. Are you using the web interface when you see that error? This looks like the kind of problem that would be caused by a WordPress editor app (or plugin) being confused. If you are using something other than the WordPress website to edit your blog, could you try switching to the online editor and seeing if the problem keeps happening?
