I'm a .NET developer trying to develop some PHP applications.
I installed XAMPP on Windows without problems, then started correctly Apache and MySQL.
After that, to update my PHPMyAdmin version, I followed the following article:
https://www.ostraining.com/blog/coding/update-phpmyadmin/
But after that my MySQL service is not starting anymore. If I open the log I read the following rows:
2016-12-21 23:22:26 21c4 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

Anyone had the same problem?
Thanks in advance
EDIT
As someone pointed out, my error is the same as Making MySQL work with utf-8 in my.cnf configuration file
However the solution for such case is not working for me.
I tried to execute the mysql_upgrade but the command is obviously not working because the mysql service is stopped.
EDIT
I reinstalled XAMPP from scratch and, like previous times, it started correctly. However, after a couple restarts it is not starting anymore (always the same error).

I've installed XAMPP on windows 10 but MySQL doesn't start. Why?
I have already tried with the task manager to see if another MySQL is running, but nothing. I tried to change the port but nothing. Please help.

I have been trying mysql_upgrade, mysqld --initialize-insecure it doesn't help me.
My script feature is it running 16 threads 24 hours per day without stopping. So 16 connections are connected to DB everytime.
On mysql configuration I have set:
interactive_timeout=31536000
wait_timeout=2147483
And nothing more unusual.
I have this situation second time, when the DB was broken.
I want to know, why do I get this problem and how to solve it.
I open the XAMPP (7.0.23) Control Panel (v.3.2.2) and start Apache and MySql. Apache connects immediately, but MySql takes a long time to display the port (3306) on the panel and start the connection. I already changed the MySql port for others but it did not work. I've also reinstalled XAMPP twice without success.
Using Win 10.

The log seems ok for me. Maybe you have permission problem, try (right click) run as Administrator the Xampp
try check your active port, maybe used by another program. Mysql use 3306 as default port. go to your xampp folder try find "portcheck.exe" or something like that. see if your mysql port used or free.
