After translate any change on website

This plugin has not yet been tested in WordPress 4.0.

When I get to doing so, I will evaluate if their are compatibility problems.

However, there is nothing in your report that suggests that the Loco plugin is the cause of the problem. Loco does not display translations on your site, it only manages your translation files.

I’ve since discovered that WP4 deprecates the WPLANG constant.

Perhaps this is your issue?

Did this information resolve your issue? I’d like to close the ticket if possible.
