I just had the same thing happen all I get is redirected to a 404 error page with this message.
http://error.000webhost.com/forbidden.html
I went into the plug-in folder and deleted them but it still doesn’t work now. This is so annoying. I had trouble getting WP setup to work, I then had trouble installing the plugins, now this. I’d sure appreciate some help. I also followed the steps in the video above but to no avail
I’ve search for a long time and have only found others having the same problem but no solutions. It must be a bug in the software. Can you try a older version? I have 2.7.
