My project has been locked

Hi,Tom! I hope you are fine.
I´m really worry again, because I was adding the last details to my project and this modifications changed but the information date don't. So when I want to make it public so I can share the link with the professors who have to evaluate it, the link shows the project like it was since april with any changes. I try to actualized the page, but any folder appears and right now I can't even enter to the software.
Please, help!

Before you do anything else, please make a copy of your installation (I suspect somewhere in your c:\xampp folder)

Then press F12, and do a refresh. Any errors in the browser console (the window that appears when you pressed F12) shown in red?

Still the same errors in red, the only thing that changed F12 is activate the airplane mode.

Please find the Fn key somewhere and try to press Fn+F12, because you should not enter Airplane mode pressing F12. Or try to press Ctrl+Shft+i to open the browser console.

Also, I do not understand what you mean by 'Still the same errors in red', because I don't see any errors in any of your screenshots.

Right, in the console browser says four problems: Accesibility (Images must have alternate text: Element has no title attribute); Compatibility ( A 'viewport' meta element was not specified/ 'content type' header charset value should be 'uft-8' (Advertising).

And in the control panel of Xampp says in red: Error: MySQL shutdown unexpectly. This may be a due to a blocked port, missing dependencies,improper privileges, a crash, or a shutdown by another method...

Hi,Tom! Today, suddenly everything works fine, MySQL doesn't stop anymore, I have acces to Xerte, my project is actualized, the only detail now is: I made public my project and shared the link with one of my teachers but she can't acces from her computer. It's neccessary that the every person who wants to see it, must have download Xerte? There is another way to share it?
Sorry to bothering you and thank you for your time
