Some dates don't appear on my forum. I don't know, maybe when i try to translate, i have modified/deletes some things/codes...?

Yes, this is caused by your custom translation. Please review your translated strings and ensure that they have the same amount of variables  as the original English string 

I have the same problem. Seems to be random, and not affected by translation.

Do you get the same issue on a default unmodified English language pack? If so, submit a ticket. But that said, 99% of the time this issue is caused by an out of date translation as Daniel alluded to.

for me happens ramdonly too

I have revised the translation but I'll switch to the english version and see if it resolves

Edit: Yes I have switched to english default and can confirm it resolves the problem.
