I post and change content from several computers into a remotely hosted v2.0.1 or 2.0.2 install. I now run into the "enable sending... etc." error all the time on any of the computers that run ZoneAlarm. However, I believe the school's IBM R51 laptop -- running a different AV package -- consistently allows me to post, update pages, etc.
I have followed most of the directions except those which call for changes at the hosting end, as that is a little more risky. I don't have the time to devote to babying the blog, so plan to find another technology to use for the classroom site.
As a last resort I will check with the ZoneAlarm forums but after much searching I have not found the one fix that will work.
BTW, is there something wrong with WP's Support Codex Search today and yesterday? I get "nothing found" for searches like "ZoneAlarm" with or without checks in all or some [target] boxes. 90%+ of these ZA hassles are listed as "not resolved" despite all the efforts of the volunteers here.
Thank you, folks, for putting in the time to write back and help with issues!
