[Resolved] Can't change default language

Hello Stéphane,

Thank you for contacting WPML Support.

- Please increase MaxInputVars to 10000 or more. For this, please try to set this variables in your php.ini:

max_input_vars = 10000;
suhosin.post.max_vars = 10000;
suhosin.request.max_vars = 10000;

You may need to contact your hosting provider to set them.

- Please enable error reporting at you site and let me know if any error found.
To enable it, open your ‘wp-config.php’ file and look for ‘define(‘WP_DEBUG’, false);’. Change it to:

define('WP_DEBUG', true);
define( 'WP_DEBUG_DISPLAY', true );

=== If still issue persists, please backup your database and website ===

✙ I would additionally need your permission to de-activate and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important.

Thank you

Hi Stéphane,

I can not see wp-admin login screen due to errors that mostly coming from your theme and child theme as you can see in attached screenshot. Can you please activate default(twenty seventeen) wordpress theme and see if it resolve errors.

FTP login info that you have provided is not working here as you can see in attached screenshot. Could you please provide me working login please. I have enabled private input box for your next reply.

Thank you

Hi Stéphane,

FTP login info still not working. I have activated default theme and deactivated all the plugins that are not related to WPML but issue still there. Then I install File Manager plugin to enable error reporting to see errors that causing this issue but this plugin not showing it’s menu due to some issue in your installation.

Can you please provide me working FTP please, so that I can debug it further.

Thank you

Hi Stéphane,

I have thoroughly debugged your site and this issue and finally I have found out that ‘SG Optimizer’ plugin causing this issue.

I have fixed this by disabling memcache option from ‘SG Optimizer’ plugin. Now WPML working as expected. Can you please check and confirm?

P.S. Your theme is still throwing errors when we enable error reporting as you can see in attached screenshot. I recommend you to please fix those errors to avoid inconvenience in future.

Thank you
