I just got Server Error 500 on my blog on androidtutorialpoint.com
Android Tutorials . I reloaded many times but still same error shown. Finally following change helped me.
Go to your ubuntu terminal and then to the path /var/www/html/wp-content/. Here you will see a folder named “plugins”. Change this name to plugins_1 (sudo mv plugins plugins_1) and it will resolve the problem.
I hope it will help.
