Title: Fatal error / Avada theme Last modified: August 21, 2016 --- # Fatal error / Avada theme * [aaaaaaaaaaaadsjkfjksdjfksdjfksdjfksjdfkjsdkf](https://wordpress.org/support/users/dadcz/) * (@dadcz) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/) * Hello, * getting: Fatal error: Call to a member function get_default_language() on a non- object in /home/content/16/10428016/html/psfest/wp-content/themes/Avada/admin/ index.php on line 62 fresh install of Avada 3.2.1 and setting up Polylang 1.2 plugin. * Can be activated. * When setting polylang and adding first language I’m getting this fatal error and I need to manually remove plugin via FTP. * Not happening with polylang 1.1.6 * How I can go back to 1.1.6?

This can be a temporary solution. You should ask the Avada author to add a test to avoid this fatal error. * Thread Starter [aaaaaaaaaaaadsjkfjksdjfksdjfksdjfksjdfkjsdkf](https://wordpress.org/support/users/dadcz/) * (@dadcz) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306125) * Thank you for your quick reply! * I’ve already posted to Avada devs. * Are there some database changes that were done by installing polylang 1.2 (and trying to activate language) that need to be undone? * Thank you! * David * Plugin Author [Chouby](https://wordpress.org/support/users/chouby/) * (@chouby) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306127) * Yes there are. Did you make a DB backup before upgrade? * Thread Starter [aaaaaaaaaaaadsjkfjksdjfksdjfksdjfksjdfkjsdkf](https://wordpress.org/support/users/dadcz/) * (@dadcz) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306133) * No, unfortunatelly I did not. My bad habit, doing only before wordpress core updates… * Plugin Author [Chouby](https://wordpress.org/support/users/chouby/) * (@chouby) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306134) * Give me some time, I will provide you a procedure. Or maybe we make this line 62 work. As you prefer (hacking the theme will also be a temporary solution). * Thread Starter [aaaaaaaaaaaadsjkfjksdjfksdjfksdjfksjdfkjsdkf](https://wordpress.org/support/users/dadcz/) * (@dadcz) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306135) * Many thanks! * Plugin Author [Chouby](https://wordpress.org/support/users/chouby/) * (@chouby) * [12 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-avada-theme/#post-4306158) * You will have to create to copy paste [http://pastebin.com/0TdQzQLv](http://pastebin.com/0TdQzQLv) in a text file to create a custom plugin.

What you must not do is delete it using the red link in plugins table (because in that case Polylang removes all its data). * Running the revert plugin should work. What is does is just removing Polylang 1.2 data, and downgrade the Polylang version number (to allow future upgrades to run smoothly). * Polylang 1.1.6 data are not removed by Polylang 1.2 (just for cases like yours when something went wrong).
