socialcal does not appear when creating a node

Same behavior here. So when the node is displayed it's just empty.
It seems Drupal is looking for a file that doesn't exist in the socialcalc library:

Warning: file_get_contents(sites/all/libraries/socialcalc/socialcalc.min.js): failed to open stream: No such file or directory

Well, I guess it's not very orthodox but I made it.
I just put on google the path of the missing file.

And Google answered me with a file listing of some website who just forgot to assign the right permissions to the whole folder: http://tis.ndt.ee/sites/all/libraries/socialcalc/

So I downloaded the missing files, I put them in my website and the sheet magically appeared.

Yes, it does need access to the socialcalc library to display. I assume that is what you did (or gave access to that library).

Closed as I believe it was a permissions issue to library.

No, it's not. The new version of the library missed some files. I added them.
