I went through the tedious task today to upgrade wordpress. So, now not only all apostrophes and speech marks are replaced by some code, which looks incredibly stupid, also something is wrong with the taggin plugin. I’m not surprised about the tag thing, since my former wordpress version was really outdated and the plugin is probably wonky due to the new version. I’ll remove all tags and the plugin and switch to a new one. This might take a little while, sorry.
As to the apostrophes, I changed thm in the last few posts, but haven’t got the time to correct each and every post. Maybe when I’m getting really bored, I will. Sorry again!
