After learning the forums weren’t really functional anymore, I spoke with Ryan, and was able to get a copy of the data. After some fiddling around, I’ve imported them locally, and now you can access the support forums here. So, moving forward, if you have support questions, please post them there!
I’ve also release v184.108.40.206 of WP-Slimbox2, to fix an issue introduced in v1.1.3 that cause some installs not to function properly. v1.1.3 also updated the version of Slimbox2.js that was being used to support the update to jQuery used in WP 3.6.
I’m hoping to find time to work on a more significant update in the coming weeks, so stay tuned!
