I just wrote a post and published it. I looked at it (like I always do) and the title has not spaces in between the words.
Looking more into it. All of them have no spaces !! I did not do a post yesterday tho I did two the day before. I believe I upgraded a plugin (don't know which one) but I tried to deactivate them and still nothing has changed. I did view it from preview and not the complete 'real' post.
Would I have to deactivate the plugins again and look at the real post ?
