Yesterday I updated _The S.T.E.A.L. Saga _to Wordpress 2.5.1. I thought the upgrade would be painless, but I was wrong. First of all, the auto plugin updater kind of confused between the various plugins, so it marked some as updateable although they weren’t. Then, some plugins (albeit incompatible), disappeared from the plugin list (the fix was downloading a more recent version).
The biggest issue was, however, the mangling of my .htaccess file due to a wrongly-generated permalink rule that was without a trailing slash (/). Such a badly done .htaccess would cause:
Problems when loading the pages
Problems with admin panels (no such page errors and the like)
Most importantly, it would cause an enormous load on the server (and with shared hosting, it is a problem)
It took me at least 30 minutes to find out what the cause was. Removing .htaccess did not help, I had to remove it then change the permalink to the default value, and then change it again. Now it works, but what a bother for a seemingly “simple” upgrade.
