MySQL has crashed

[matlin]

Hey there

I am new to MySQL an everything to it. I am in school and we are currently learning us how to use Wordpress and build our own themes etc. Everything was working fine until I updated my computer. It started with me not beeing able to access word due to my username and password not beeing correct (it was I checked it) and then I tried to repair the user which did not work. I then continued to erase the database cause I thought that it might work, it did not. Furthermore, I ran a code an now nothing is working.
I have an assignment that needs to be handed in tomorrow and my teacher is not responding to my messages. Is there anyone who knows what I am supposed to do?

Kind Regards
Matilda AKA a student in need


The error log will be down below if there is anyone who can see what I did wrong.

Did you really erase/delete the database content? If so, and you do not have a backup, then for whatever database(s) you erased, the work done to date is gone.
Which database(s) did you erase, just the one hosting your WordPress site? Others? If the answer is others, that is definitely not good, as some of those are related to MySQL, and phpMyAdmin. I believe there are copies of those in files under the xampp install folder, but have neither verified that, or used them to restore data.
If you only erased your WordPress site's database, you should be able to restore that from a backup. You do have a recent backup, correct?
When I load MySql the error log shows pretty much what you have above, with the addition of a handful of entries. I am wondering which database you erased... and sure hope you have a backup, and an understanding professor
Below are the additional lines I see in my log:
