Honestly, the frustrated smile (though still a happy one) doesn't leave my face while attempting this pset8 for a second week in a row. I had permission issues, and I have issues with addMarker and removeMarkers functions, which should have been the easiest part of the task.
I have decided to start it all over again; have deleted all my code and the whole pset8 I had on IDE, have downloaded a new one and have started working on it from scratch.
After downloading all files and setting correct permissions, I have opened my Mashup window; it works. Tried to head to https://ide50-username.cs50.io/phpmyadmin (username = my name) and got the following error:
phpMyAdmin - Error The mysqli extension is missing. Please check your PHP configuration. See our documentation for more information.
The documentation leads to the following page http://docs.phpmyadmin.net/en/latest/faq.html#faqmysql
I am among less comfortable and I honestly, already having so much technical troubles with this pset, I am not confident in attempting to change IDE settings. Please, advice me on what I shall do. I can't finish this pset in such a long time. Thank you very very much!
