[SOLVED]user data is displayed as ???????,

13 years 2 months ago #136842 by emakki
Probably there is a utf-8 encoding somewhere in the code. This happened to me before in Arabic with one of the components.

For those who face the ??? question marks issue with utf. There is a solution script I found online that converts everything in the database to utf-8 including the fields. Just use the script and enter db connection information.

Make sure you save as index.php and upload to a new folder.

Good luck.
