Hello,

I've been trying more than 10 times to post my feedback but everytime i press the submit button, I'm redirected to error pages like this one :

"General Error

SQL ERROR [ mysql4 ]

Incorrect string value: '\xF0\x9F\x92\x99\x0AI...' for column 'post_text' at row 1 [1366]

An SQL error occurred while fetching this page. Please contact the Board Administrator if this problem persists.

Please notify the board administrator or webmaster: admin@fanmail.biz"

Did someone ever had this problem ?
I could really use some help.
I've posted feedback before and never been confronted to this !

Thank you,
Clara

[Edit:]

I've figured it out. It wasn't working cause I put heart emojis in my post.
