    Hi. This is a notice to others hosted on Siteground.

    I was getting an Error 0 from Loco Translate when I tried to create a new translation. The cause was an HTTP 400 response from admin-ajax.php. I disabled the SG Optimizer plugin and it works fine now.

    Thanks for posting this! I’ve had countless reports of this issue that I’ve not been able to solve.

    I don’t understand why a status 400 would produce a status 0
    on the front end, but probably I’m missing something about what’s going on.

    Regardless, I have favourited this post and will add SG Optimizer to my help docs.

    Glad to help.

    The HTTP response code is 400, but the response body is 0. There are quite a few wp_die( '0', 400 ); lines in admin-ajax.php. They all seem to be related to one of 3 different action parameters being missing.

    I’m not sure exactly why SG Optimizer causes this. It may be stripping query params for some reason. I know some caching systems strip query params to increase the cache hit ration, so it’s not out of the question.
