I resumed the course with this video after two days off and now getting several errors. I'll just copy them here. They also appear when I just start the server and the "insecure world writable dir..." errors appeared from day 1 but didn't disturb my program so far. Any Ideas on what this might be? I also couldn't really complete the last video - it had problems with the attr_accessible part...
Any help appreciated :) Cheers! P!

133 PointsFor what it's worth, here is the solution: http://stackoverflow.com/questions/17371334/how-is-attr-accessible-used-in-rails-4 problem occured when with rails 4 strong parameters where used for this... I used the way of installing the gem..

5,167 PointsI tried the solution by adding protected attributes but i still get this error when i run bundle:
Bundler could not find compatible versions for gem "activemodel":
In snapshot (Gemfile.lock):
activemodel (= 5.0.0)
In Gemfile:
rails (~> 5.0.0) was resolved to 5.0.0, which depends on
activerecord (= 5.0.0) was resolved to 5.0.0, which depends on
activemodel (= 5.0.0)
rails (~> 5.0.0) was resolved to 5.0.0, which depends on
activerecord (= 5.0.0) was resolved to 5.0.0, which depends on
activemodel (= 5.0.0)
protected_attributes was resolved to 1.0.0, which depends on
activemodel (< 5.0, >= 4.0.0.beta)
web-console was resolved to 3.3.1, which depends on
activemodel (>= 5.0)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

It occured after Creating the new attr_accessible in the "Build a simple ruby application" trail.
