hello all,

I still continue my tests on a local server of HUBzero cms, and I come to you this time to ask some questions:

1 – hang my tests I found some error code and I managed to fix them in registration and groups component. (I guess because the cms works and I get better results after each step)

2 – If anyone can guide me to understand the role of the components “com_hubgraph” and “com_pdf2form” thank you in advance

3 – after creating a group on my site, if I click on the link “resources” I get an error page:

here is the error obtained.

One last question: In the collections component, if I click on the new collection or new post button, the page refreshed with nothing!!! I am not redirected to the creation form of collection or creation of post

thank you in advance for taking the time to answer me regards
