I stopped using K2 at version 2.6.2 (23/11/2012).
My question is:
Have you fixed the title alias URL problem with the greek fonts?
Topic titles like:
"Διαγωνισμός: Κερδίστε δώρο"
were causing the news item to collapse after being posted, so some (not all) users were redirected to this page:
Attachment not found
That's the most important issue I've ever had with K2. I was posting something with a greek title, I was forgetting to click on the news item to see if it works (and it SHOULD work as with all other editors) then this was happening and all users were complaining.
I own Gameworld.gr which is the first gaming community in Greece. The result that you see in this picture has happened dozens of times! Our users are complaining for months.
This happened again today in this news item which had a greek title:
www.gameworld.gr/contests/item/14872
Next time this happens we will blame your company for causing this issue. This is a *GAMEBREAKING* bug as we say it! It makes your component unusable, even though It happens like in 1% of our news items.
We paid for a component in order to work so we want a straight answer. If we are about to pay to have latest version of July and this bug persists we request that you solve the issue within days OR a full refund. Are you ok with that?
ps. And make a greek forum. You are a greek company.
