Function _load_textdomain_just_in_time was called incorrectly - error with multisite setup

[ankitguptaindia]

Describe the bug

When activating the Restricted Site Access plugin on a WordPress multisite network, the following error appears in debug logs. This issue occurs specifically in a multisite setup when a subsite's language is changed to a non-English language.
The plugin functions correctly on a single-site installation but fails on multisite due to translation loading happening too early in the WordPress lifecycle.

Steps to Reproduce the Error

1. Set up a WordPress Multisite Network

   • Install and configure WordPress as a multisite network.
   • Choose the subfolder structure when setting up the network.

2. Add a New Subsite

   • Navigate to Network Admin > Sites > Add New
   • Create a subsite under the subfolder structure (e.g., example.com/subsite).

3. Activate the Plugin Network-wide

   • Go to Network Admin > Plugins
   • Install and Network Activate the plugin that triggers the error.

4. Change the Subsite Language

   • Navigate to Dashboard > Settings > General of the newly created subsite.
   • Change the Site Language to a language other than English (e.g., French or Spanish).
   • Save the changes.

5. Enable Debug Mode

6. Reload the Subsite

   • Visit the subsite's frontend (example.com/subsite) or dashboard.

7. Check the Error Log

   • Open the wp-content/debug.log file to verify if the following error is logged:

     PHP Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the restricted-site-access domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.)
