I’ve just uploaded Weaver 1.0.1. It has a few new features and a few bug fixes. See the Release Notes.
Important! We strongly recommend that you install the Easy Theme and Plugin Upgrades plugin, available at WordPress.org, before trying to install the latest Weaver II update.
After you install Easy Theme and Plugin Upgrades, go to the Themes:Install admin page. Click Upload, and you’ll get the Theme Upload page. Be sure to select Yes for the “Upgrade existing theme?” question. Then simply select the Weaver II zip file, and upload/activate it.
