Problem:

HTTP Headers plugin - Call to a member function switch_to_locale() when String Translation is active

https://wordpress.org/plugins/http-headers/

Solution:

1. Take a backup of your site in case something goes wrong.

2. Edit with code editor the following file in the HTTP Headers plugin folder.
/wp-content/plugins/http-headers/http-headers.php

3. Replace the following lines 1417/1418

add_action("added_option", 'http_headers_option');
add_action("updated_option", 'http_headers_option');

with:

add_action("added_option", function() {
     add_action('admin_init', 'http_headers_option');
     add_action("updated_option", 'http_headers_option');});

4. This should solve the fatal error issue when saving the HTTP Headers options.

Problem: I need to show the same template in both languages, greek and english but only one works. The other shows the default layout of the theme.

Solution: There is a workaround for this issue provided by our specialists. Please follow these steps to apply the workaround:
- Create a full backup of the site.
- Modify elementor-pro/modules/theme-builder/classes/conditions-cache.php Lines 96 - 101:

$query = new \WP_Query( [
            'posts_per_page' => -1,
            'post_type' => Source_Local::CPT,
            'fields' => 'ids',
            'meta_key' => '_elementor_conditions',
        ] );

$query = new \WP_Query( [
            'posts_per_page' => -1,
            'post_type' => Source_Local::CPT,
            'fields' => 'ids',
            'meta_key' => '_elementor_conditions',
            'suppress_filters' => true,
        ] );

Important note - This workaround has two effects:
1.- The conditions start working for all languages
2.- When you search for posts or pages etc in the Display Conditions dialog, ALL language posts are returned. This is more of a cosmetic issue but just so you know.
