My website is showing the wrong characters as you can see in the attached image, taken from google analytics:
Now, the problem is that these characters only show SOMETIMES, which I find very strange.
I've tried changing the database collation to utf-8 as per this post.
And I've also tried using Admin tools "Change database collation" several times, and "Repair & Otimise tables" but nothing works.
Have also cleared cache and temp directory.
Can anyone please help?
