Hi,
I have somehow a very similar phenomenon. My URLs in posts are automatically transformed into links and I have no clue why. I had the plugin ‘Autolink URI’ and ‘Google Analytics for WordPress’, which both generate autolinks. After uninstalling them the autolinking still works and I don’t know why. It does not seem to be my Arras-theme.
Autolinking is very convenient, I just wanted to change the links to open as target=”_blank” – that’s why I started digging into it.
Any comments on this?
