Installation and server related problems

Hi, After activation h5p I get the following error:

Fatal error: Call to undefined function wp_safe_remote_get() in /home/ecdlbgx0/public_html/wp-content/plugins/h5p/admin/class-h5p-plugin-admin.php on line 344

I haven’t idea how did I fix it?

Thank you 

Hi.

I installe  the h5p plugin ( automatic install in WP admin), but when I try to activate it, I get the following error:

Parse error: syntax error, unexpected T_FUNCTION in /home/www/0121b250f6e36769b12c11376e25e1b0/web/wp-content/plugins/h5p/h5p-php-library/h5p-default-storage.class.php on line 180
