I tried to add the Behance Portfolio Manager plugin to my WordPress site to link my Behance Portfolio. I tried it on different computers, but the search window just showed the spinner.
I researched it a bit and several suggestions were to edit the wp-config file, which I really didn’t want to do.
I had added WooCommerce the other day, but didn’t finish going through the complete install. I thought maybe that had something to do with it.
I deactivated WooCommerce, then deleted it.
I tried searching for Behance Portfolio Manager again, and it worked!
Lesson here: if something suddenly stops working, go back to what you did recently and undo it, if you can. It worked for me. Happy WordPressing!
