Anyone know how to fix fix that ????? i got more than a 1000 line like this

It's a translation notice. Most probably, you have mismatched free and pro. So make sure you are using the latest version of both plugins. Another reason can be: another plugin inited the translation before init and then fluent-community is showing these fro the core wp function.

So you can fix these or another easy solution is, you can disable wp debug mode.
