Big problem after install and activate pro version

Hi there.

The free version of the plugin was working fine.
I bought and install the new version (deactivating the old version and then uploading and activating the pro version as you recommend).

After the activation, well, glosary is working fine, but now I CAN’T create or update any post, page or glosary item, i actually can’t do nothing in my wordpress.

AS i told before the free version was working fine.

If I open a post page or glosary item, or create a new one, on update or save I got this in a horrible blank white page:

bool(false) bool(false) bool(true)

Also in my front end I got this before the search form:

I’m including screenshots with the errors and the credentials to access wordpress. I need a solution for this issue please as soon as possible please.

Thanks in advance.
