[SOLVED] Error after update to J3.5.0, illegal collation error in FLEXIcontent backend

Hello !
I use the 3.0.13 version of Flexicontent
I just updated my website in Joomla from version 3.48 to 3.5 and I can not do anything in the administration because I have the following message:

"1267 Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation '=' SQL=SELECT COUNT(*) AS total1, ( SELECT COUNT(*) FROM `#__flexicontent_items_ext` AS ie JOIN `#__content` AS i ON ie.item_id=i.id WHERE 1 ) AS total2 FROM `#__content` AS i JOIN `#__flexicontent_items_tmp` AS ca ON i.id=ca.id JOIN `#__flexicontent_items_ext` AS ie ON ie.item_id=i.id WHERE 1 AND i.`title`=ca.`title` AND i.`state`=ca.`state` AND i.`catid`=ca.`catid` AND i.`created`=ca.`created` AND i.`created_by`=ca.`created_by` AND i.`modified`=ca.`modified` AND i.`modified_by`=ca.`modified_by` AND i.`publish_up`=ca.`publish_up` AND i.`publish_down`=ca.`publish_down` AND i.`version`=ca.`version` AND i.`ordering`=ca.`ordering` AND i.`access`=ca.`access` AND i.`featured`=ca.`featured` AND i.`language`=ca.`language` AND ie.`type_id`=ca.`type_id` AND ie.`lang_parent_id`=ca.`lang_parent_id` "

Do you have an idea of the problem ?
Thanks
