[Resolved] fatal error

[Hemmerick]

Hello,

I am getting the following error after GP theme installed and activated:

Fatal error: Call to undefined function is_customize_preview() in /home/iasp9999/public_html/wspd2018/wp-content/themes/generatepress/inc/css-output.php on line 738

php memory-limit set to unlimited -1

When I try tp customize template, I get the following error message:

https://iasp.info/wspd2018/wp-admin/customize.php?theme=generatepress
Fatal error: Call to undefined method WP_Customize_Manager::get_panel() in /home/iasp9999/public_html/wspd2018/wp-content/themes/generatepress/inc/customizer.php on line 180

Hi there,

is_customize_preview() is a core WordPress function, added in WP 4.0: https://codex.wordpress.org/Function_Reference/is_customize_preview

What version are you using?

If you’re using a later version than that, you might need to re-install the WordPress files to make sure all functions exist.

Thank you Tom. The update worked.
