Topic: PHP warning for item in \include\functions.php
Last week I found 8 times the following PHP warning in the Apache log file (nothing changed in my server or PHP configuration):
PHP Warning: htmlspecialchars(): Invalid multibyte sequence in argument in D:\\Programme\\Apache\\htdocs\\forum\\include\\functions.php on line 21,
....caused by 6 different clients from different countries (USA, China, Czech Republic, however, the logged IP's could be proxies or faked)
I just want to notify you about. Probably it is some unimportant warning, but may you want to know about it.
