Plugin dont save review if name cirilic

While nowhere to wait for help, trying to understand myself what it is, with my meager php and js.
If the name in Russian, it does not keep a database comment. Check in on phpmyadmin.

[ 1,177 lines of PHP code redacted. ]

In the name field corresponds to the field in the database “reviewer_name”.
At what is a record in the database with one Cyrillic name as it is in the past, the last time I do not understand? Recently there have been many updates ch. Encoding blog checked UTF-8

Please don’t post code like that in these forums. More than 10 lines becomes not very useful.

This is the file you pasted into the post.

Ok. Thanks.

I faced the same problem recently. Solved by changing the collation of all fields in the “wpcreviews” table from “cp1251…” to “utf8_general_ci”.

Try that. Peace.
