This bug does not affect every user, which is probably why I didn’t notice it until now. Also, it only seems to happen if you have an old version of Joomla! previous to 1.5.10.
This bug only affects the main blog when the EveryHome template is used.
If you see an error like this:
Fatal error: Class ‘JCache’ not found in /media/wpmu/themes/everyhome/home.php on line 23
The please download this file.
Rename it so it doesn’t have the .txt extension and upload it here:
/media/wpmu/themes/everyhome/home.php
We can also take care of this for you if you submit a support ticket with FTP access to your site.
