Hi,
thanks for your prompt answser. I have this error (mydomain.fr is a fake) when your plugin is activated :
FastCGI: server “/var/www/clients/client1/web6/cgi-bin/php5-fcgi-*-80-mydomain.fr” stderr: PHP message: PHP Fatal error: Call to undefined function et_get_option() in /var/www/clients/client1/web6/web/wp-content/themes/Divi/functions.php on line 7987, referer: https://mydomain.fr/wp-admin/themes.php
it seems it is an error on Divi but when i desactivate Loco translate all is ok.
I send a message to Elegant Themes too
PS : i use Php 5.6 on a debian Jessie Server
Regards
Ben
