Missing localization strings on the login page

After installation of WebAsyst the login page may contain no text strings as shown in the picture:

In this case the following parameters should be checked:

1. Parameter LANGUAGE in the XML file located in directory dblist/ must have value "eng". If the value is empty, enter the correct value into the file and save it.
2. Permissions of file published/AA/localization/.cache.php must allow the web server to modify its contents. Assign wider write the permissions to that file and directory published/AA/localization/ if necessary.
3. File kernel/languages.csv must be readable by the web server. Assign wider read permissions to that file.
4. Directory temp/ must be writable and readable by the web server. Assign wider write and read permissions to that directory.
