Fatal error when installing module LanguageSupportPageNames

[antoiba86]

I am a bit confused, because I don't know how to solve this problem.

When I install the module Languages Support - Page Names, my web falls apart.

I have all the necessary modules installed as Language support for example.

This is the error I get in the admin panel.

Warning: Invalid argument supplied for foreach() in /hosting/www/antoibaprogramming.com/public/wire/modules/LanguageSupport/LanguageSupportPageNames.module on line 107 Warning: Invalid argument supplied for foreach() in /hosting/www/antoibaprogramming.com/public/wire/modules/LanguageSupport/LanguageSupportPageNames.module on line 198 Warning: Invalid argument supplied for foreach() in /hosting/www/antoibaprogramming.com/public/wire/modules/LanguageSupport/LanguageSupportPageNames.module on line 1011 Warning: Invalid argument supplied for foreach() in /hosting/www/antoibaprogramming.com/public/wire/modules/LanguageSupport/LanguageSupportPageNames.module on line 1011 Warning: Invalid argument supplied for foreach() in /hosting/www/antoibaprogramming.com/public/wire/modules/LanguageSupport/LanguageSupportPageNames.module on line 1041

And this in the front-end.

At line 107 module iterates over $wire->languages, if it's not an iterable object, i.e. null, you'll get this error. 

If you can, try uninstalling all language modules, then reinstall starting from language support module.

I did as you say, but now I have a new error when trying to install from scratch.

And I see that it is a common problem.
