Hi,
Can you help me to resolve this issue?

I’m running WordPress on PHP 8.0

Uncaught TypeError: count(): Argument #1 ($var) must be of type Countable|array, int given in wp-content/plugins/gbi-buy-now/funciones/funciones.php:42

Stack trace:
#0 /wp-includes/class-wp-hook.php(303): gbibn_comprobar_sesion()
#1 /wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters()
#2 /wp-includes/plugin.php(470): WP_Hook->do_action()
#3 /wp-includes/template-loader.php(13): do_action()
#4 /wp-blog-header.php(19): require_once('...')
#5 /index.php(17): require('...')
#6 {main}
  thrown, file: /wp-content/plugins/gbi-buy-now/funciones/funciones.php, line: 42

Hi,
I know that it’s not plugin fault, mostly it depends on .htaccess or server-side. But have you had this kind of problem before? and what was the solution?

Thanks
