The biggest remaining issue in my building this site is the Wiki, Blog and statistics (PiWik) are giving fairly frequent “500 Internal Server Error”. So if you experience one, it would be great if you can provide details of what you where trying to do (page) and the date/time + time zone, or if you have any suggestions to fix this on a WordPress/MediaWiki site, I would really like to hear your advice.
My hosting services advice is that most likely something to do with .htaccess (Linux hosting). I have not manually edited any of the site .htaccess files, although admin settings for WordPress permalinks and caching plugin have updated the files. Also spent a fair bit of effort bedding down the site and fixing a heap of email and site technical issues. Content issues will be tidied up “as time permits”, or for the wiki probably needs to be blown away and re-installed to easily fix all my property/type errors (did not RTFM).
