Hello,

You can try by adding following lines in your CSS file.

.container {
    width: 100%;
}

Changing PHP version certainly cause compatibility issues,
To find out exact issue, make the following changes in WP-Config.php file to get exact error.

1) if you find below WP_DEBUG set to false then set it as true

define( ‘WP_DEBUG’, false ); ===> define( ‘WP_DEBUG’, true );

It will trigger the “debug” mode.

2) Also, change WP_DEBUG_DISPLAY from false to true

define( ‘WP_DEBUG_DISPLAY’, false ); ====> define( ‘WP_DEBUG_DISPLAY’, true );

It will displays the warnings and errors.

Then check your website. Now it will shows the exact error.
