[Use v3.0.14+] 1267 Illegal mix of collations

Hello,
After updating Joomla from 3.4.8 to 3.5.1, I get this error each time I try to access items or categories on the back-end :
1267 Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '<>' SQL=SELECT COUNT(*) FROM #__content as i JOIN #__flexicontent_items_ext as ie ON i.id=ie.item_id WHERE i.language<>ie.language LIMIT 1

What am I supposed to do to solve this?

Thanks for any help.
Flo

Hello

have you searched the forum ?

there are 6 other threads on this, you could have posted in 1 of them

also you do not mention the FLEXIcontent version that you are using, since this is supposed to have been fixed with v3.0.14-rc2a or later

I'm sorry, I should have look in the forum before posting!
I did... after... ooops!
So now I'm trying to find out which version of flexicontent I use, but... I cannot access to components/flexicontent, so I dont know how to find out which FC version I use...

EDIT: I checked in my notes (I write down everything I do when I change something important), and I found out : I'm still under v3.0.13 :blush:
So I'm gonna upgrade to 3.0.14 right now. Sorry..

Hello

you do well to report bugs

only please search forum first
and also mention Joomla / PHP / Mysql / FLEXIcontent versions

Yes, I understand. I was a little in panic when I saw this appear, so I forgot to check first, I was so convinced it was going to be difficult and unique ...
I just updated FC to 3.0.14-rc2a, and everything seems to work perfectly. Thank you

Hello

v3.0.14-rc2a:
if you are using sharedmedia field make sure you get API keys
you cannot save old values in item form without them

v3.0.14 fixes this, so that you can save existing values without yet adding an API key

also since you had reported this :
navigation buttons when coming from module now works, please confirm it
