Hmmmm...
XAMPP version 7.4.21-0-VC15 been working great. This morning, mySQL fails to start. Not sure why or what course to take; so thought I'd throw in up here.
Also wondering if it's just as efficient to do a fresh install of the most recent version of XAMPP, or, try to see what is causing the fail (latter preferred).
I do wish there would be a way to attach a document here, since I read what was hoped for by Friends when such a post is made. Maybe I'm just missing something. I'll try to put it all in here.
Thanks in advance.
XAMPP version
This should contain;
• the full filename of the downloaded xampp installation file: xampp-windows-x64-7.4.21-0-VC15-installer(1).exe
XAMPP version number: 3.2.4
operating system version
Major version: Windows 10 Pro, v.10.0.19043, Build 19043
XAMPP installation path
C:\xampp\
any configuration changes made since installation
Did you execute some script? No
Or used the XAMPP security script? No
Or changed anything in the config files? No
full qualified issue report
This should contain three information
• Actions: Start Windows, start XAMPP control panel, allow Apache and MySQL to start, open localhost installs.
• expected reactions: Smooth, uneventful success and operation.
• received reactions XAMPP starts, Apache starts successfully, MySQL starts then fails
This also includes full error messages
XAMPP control panel log
Either from the XAMPP control panel log window itself or from the \xampp\control-panel.log: Unfortunately, file inadvertently cleared.
Log file contents of the specific component
Mostly accessible with help of the Logs buttons in the control panel
\xampp\mysql\data\mysql_error.log: See below:

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients
[client]
# password = your_password

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port = <port>
