I am running Mediawiki 1.22.2, PHP 5.46, MySQL 5.5.27 on Ubuntu 12.10.
When I setup the Wiki I was able to change the logo to a new one. I then edited the Main Page and now the logo is gone. The logo does appear from time to time on different pages but no longer appears when I go to my main page. Any pointers on how to correct this.I have tested this on MSIE 11 and Chrome Version 34 (latest at this time) on Windows 7.
