The extension is approved. Maybe it's a mistake, but no one answers my question. The response from the moderators was never received. What should i do?

More than a week trying to upgrade extension in Opera store. I do standard actions. I packed extension folder with the key file by means browser in the .nex file and upload this, when the site get the following:

Internal Server Error. We are experiencing some problems. Please try again later.

And so all the time. I looked around the store, there are new updates additions, and I have this eternal error. What could be wrong?

Более недели пытаюсь обновить дополнение в магазине Оперы. Делаю стандартные действия.
Запаковываю папку с файлом ключа средствами браузера в файл .nex и когда загружаю на сайт получаю следующее:

500. Internal Server Error. We are experiencing some problems. Please try again later.

И так всё время. Смотрю по магазину, есть свежие обновления дополнений, а у меня эта вечная ошибка. Что может быть не так?
