Hi, you should either go to the item page of the theme and ask the author in the comment section, or go to the profile of the author (just click on his name on the item page) and use the contactform on the bottom right.
If you need a starting point with your homepage looking like the demo where you can edit everything to your need you should ask the author for a demo xml file (sometimes they are even included in the file from themeforest).
And then you have to import that file.
A pretty extensive tutorial on how to do that can be found here: http://thebuckmaker.com/how-to-install-wordpress-themes-and-demo-content/
I hope that will help a bit.
Im starting to feel like the coyote chasing the roadrunner, but god is my witness one of these days my tunnel painted on a mountain trap will work!
If you use get_the_terms you have to use ‘portfolio_cats’ but you have to work on the output a bit more since an array of objects gets returned.
See the codex page: http://codex.wordpress.org/Function_Reference/get_the_terms
And especially the “A Basic Example” section on how to proceed.
Edit: Seriously, beat again
This should do what you need:
$post_cats = get_the_terms($post->id,'portfolio_cats');
Edit: WPExplorer beat me to it, if you want the output to be hyperlinks use his solution, mine returns the categories as text.
A few words are ridiculous hard to read, but a reload or two usually solves this, most of them are ok.
There is also a big difference in trolling a serious thread where people discuss a real topic or trolling in a thread that is nothing but a troll thread in the first place and only was created to stir things up and make people feel bad.
I dislike the first, but trolling a troll never hurt anyone
In a perfect world you should be able to just update the plugins.
But in order to be safe i would recommend updating them one at a time and then checking if everything works. If yes the next plugin can be updated, if not just delete the updated plugin and install the original from your downloaded file again.
Well that depends.
Since support is not mandatory you cant do much in that regard.
But if they file was advertised with functions that do not exist and / or work you can request a refund from the envato support team.
But if the feedback was really good chances are the features do work and you might just have to take another look in the documentation or contact the author again for help.
