Error 500 it’s a php error, you can enable wp_debug and tell me the excect error?
Warning: mysqli_real_connect(): Headers and client library minor version mismatch. Headers:50556 Library:50628 in /var/www/html/wp-includes/wp-db.php on line 1612
Notice: Use of undefined constant ICL_LANGUAGE_CODE – assumed ‘ICL_LANGUAGE_CODE’ in /var/www/html/wp-content/plugins/wp-faq/wp-faq-plugin.php on line 2392
Sorry, nothing from my plugin.
You should contact the plugin developer.
The reason I’ve written to ypu is because when I debuged from their plugin I received:
Catchable fatal error: Object of class WP_Error could not be converted to string in /var/www/html/wp-content/plugins/post-smtp/Postman/Postman-Email-Log/PostmanEmailLogService.php on line 148
because when I deactivated POST SMTP, the problem has gone.
If you turn off the FAQ the message disappear?
can you give me a link to this faq plugin?
