MySQL session won't start on XAMPP

Question

My MySQL won't start and it shows like this:

12:50:50  [mysql]   Error: MySQL shutdown unexpectedly.
12:50:50  [mysql]   This may be due to a blocked port, missing dependencies, 
12:50:50  [mysql]   improper privileges, a crash, or a shutdown by another method.

12:50:50  [mysql]   If you need more help, copy and post this

and then this is the error logs:

for this issue go to:

c:\xampp\mysql\data\

and delete ALL FILES except DIRECTORIES.

just in case keep my.ini, if you got error again delete my.ini too.

Very Very Easy

Open xampp > mysql > backup copy everything from backup folder and paste everything in data folder copied from backup folder

Restart xampp and start all.Thanks.

If it was very easy, the question was probably not here on stackoverflow. Stating something is easy is very subjective. A good explaination how it works, often works out best – Eduard Keilholz Nov 15 '21 at 14:44
