This is more of an informative post. I recently updated to flavor 1.11 and I found that the theme options were no longer saving. I followed the advice here but neither worked. I went through each plugin and found that it was the Custom Admin bar plugin that had been casuing this and the theme now saves after deactivating and removing the plugin.
Thanks for taking the time to post this for the benefit of myself and others. I'll take a look into this and keep an eye on it to see if I can find a fix, thanks.
