Problem with translations

Hello all.

I am beginer WP user and i have problems with translate.

I installed newest script version, bought theme (on Themeforest), read some post like this http://codex.wordpress.org/Installing_WordPress_in_Your_Language#WordPress_v4.0_and_above and this http://www.designwall.com/guide/how-to-translate-wordpress-theme/, and created two files .po and .mo.

Language files copy to wp-content/language and themes/themename/languages folders.

In Settings/General change language from English to France.

What happened?

In header I have error:

Parse error: syntax error, unexpected '=' in /home/czesiu/domains/tester/public_html/wp-includes/pomo/translations.php(202) : runtime-created function on line 2

And when i try added some post, I have blank page with this errors:

Parse error: syntax error, unexpected '=' in /home/czesiu/domains/tester/public_html/wp-includes/pomo/translations.php(202) : runtime-created function on line 2
