white screen after install

same here

I get the error:

Fatal error: Call to undefined function is_site_admin() in /home/*****/domains/****.**/public_html/wp-content/plugins/buddypress-like/bp-like.php on line 248

(I replaced some lines with stars myself. Didn’t wanna publish.)

I found this too.

If you’re feeling confident you can apply my fix in your own sites.

Replace the code here https://pastebin.com/nV3bapeQ with the code on lines 225-261 of the plugin.

I’ll attempt to notify the plugin author of this too.

Thanks! It works!
My problem was that I can’t access to my desktop. But with this solution, I have been able to fix the problem, I can upgdate the database of buddy and now all is alright.
Thank philipjohn
