I can't access ide50-username.cs50.io. Please, take a look at my chmod commands. I have done them 3 times, and at the third run I have decided to do each one separately to make sure each one is correct.  I get

But I can access phpmyadmin and have created the required table pset8.places.

I didn't have any such issues during pset7; pset7 files worked, except for the one that contained email sending code; though I am still figuring out how to run pset7 on my machine.  

I will be grateful for support on this issue. Thank you very much!

 **UPDATE1:** @Matt Obert I am sorry for posting the results in comments (will delete those now) - I should have figured out that updates are the best way to post code blocks ) I understand how vexing my mistake is. Sorry. 

The answer to Problem One "Permission on config.json": my mistake, I have not posted the corrected permission of 640, which I have set to config.json after you have recommended it a few days ago; thus config.json has had rw-r-- persmissions when I performed the rest of tests. 

    -rw-r----- 1 ubuntu ubuntu  137 Nov  5  2015 config.json

**UPDATE2:** I have checked all permissions once again, compared them with your ones, and have made few corrections.

Bingo! I see the map! ))) Such a relief )
@Matt Obert Thank you very very much for helping me out! Thank you for your time and your effort. What's also important thanks to you I have learned a few new tools. Being among much less comfortable, I get excited when I learn new things )
