Is embed plugin too buggy to use on live site?
Seems to be issue after issue to do with the embed plugin and usage. So many posts on here about bugs/errors/issues that get no response, I'm getting errors on my site now too for some users, and all seem to involve embed plugin.
Any chance this plugin / the issues will be looked at by anyone soon-ish? I'm sure there'd be plenty ready to combine payment for issues to be sorted out.
