Help, changing the wp-config to use my language brakes my site

My las post i quoted the wrong portion here is my post again, sorry!

Hello I have some issues with translating my genesis install, well not really a problem with the translation nor the plug in, at least I don′t think it is.

Here is the issue:

I installed the plugin (the genesis translation one)

I uploaded to the wp-content/language the required language, spanish.

Then I changed the wp-confing PHP line to from this define (‘WPLANG’, ”); to this define (‘WPLANG’, ‘es_ES’);

The frontend works fine and the translation works just fine but can′t load the dashboard on the backend, i get this error:

Server error
The website encountered an error while retrieving https://equilibre.gt/wp-admin/index.php. It may be down for maintenance or configured incorrectly.

Here are some suggestions:

Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

Then if I change back the wp-config to define (‘WPLANG’, ”); all works fine again but no translation on the front end.

one word HELP!

Thanks a lot I really appreciate your effort and time

This most likely is related to your WordPress installation not getting enough memory to be used. Activating a language will always require more memory usage and certain hosts are using a too strict minimum for that.
