I’m having a similar issue.
Warning: mb_convert_encoding(): Unknown encoding “utf8mb4” in ../wp-content/plugins/contact-form-submissions/Admin.php on line 481
I need help with this as well, please. 🙂

xdelfino,
I have Version: 1.6.1 installed and I was able to fix my error by replacing line 481 in the file listed below;
../wp-content/plugins/contact-form-submissions/Admin.php
Original code on line 481 –
$values[$key] = mb_convert_encoding($value, DB_CHARSET);
REPLACED with –
$values[$key] = mb_convert_encoding(sanitize_text_field($value), 'UTF-16LE');
Hopefully this works for you and others with this new bug. Would be great to see an official update for the plugin.
good luck
Hi
If there’s a fix for everyone I will certainly release an update to fix the warning.
Can you confirm the value of DB_CHARSET defined in wp-config.php. It’s usually utf8 but given the warning it looks like you’re both using utf8mb4?
Hi
I confirm my value is: define(‘DB_CHARSET’, ‘utf8mb4’);
At the moment, I force in admin.php the value “utf8” instead of DB_CHARSET so i can export …
waiting for the update asap.
thank you
Hi! im having the same issue
i get the csv file with this:
<br />
<b>Warning</b>: mb_convert_encoding(): Unknown encoding " utf8mb4" in <b>/www/cerrocred.com.ar/htdocs/wp-content/plugins/contact-form-submissions/Admin.php</b> on line <b>481</b><br />
I am using the same plugin in another site, and it works perfectly but in the other site, i get this error.
What can i do?
jasongreen,
I can confirm also my value is: define(‘DB_CHARSET’, ‘utf8mb4’);
Hi
Before I release another update can you please edit the following two lines and confirm if it fixes your problem.
Admin.php replace line 483:
$values[$key] = mb_convert_encoding($value, ‘utf8’);
Admin.php replace line 504
$values[$keyFile] = mb_convert_encoding(implode(‘,’, $files), ‘utf8’);
Regards
Jason
No, it still won’t work,
i get the same error.
I didn’t try to deactivate it or even uninstall it and then get it again, cause i’m afraid i will lose all the submissions i got so far.
Is there any way to back that information up?
