I recently did an upgrade to 1.12 and decided I wanted to also add some buttons to the toolbar. I have already added the TexBox extension and that button was installed and working. I then proceeded to add a slew of other buttons using the ones from other users and following the instructions, I added them to Mediawiki:Common.js & they worked fine. However after a few other upgrades i.e. Apache2 and a few others, now the buttons do not appear on my machines, inside my intranet. I have been told, and have seen myself, that they do appear when the pages are viewed from outside my internal network. I figure I have crapped up something with my system, but can not tell what is wrong. Any ideas are appreciated. BTW; I am very much in a learning mode, so pointing to any resource is great. Along with the disappearing buttons the left menu panel is now below the page and the decorations at the very top of the page disappeared. Is this normal in 1.12 or did I alter something. I am using the CologneBlue skin. This is a non-production site that I am learning on. http://www.physicswiki.net Thanks!! - John Foster
