Problem: The client reported that the menu language switcher disappeared from their website, while the widget language switcher was still visible. Additionally, they were concerned about the WP memory limit and its impact on their website. Solution: For the disappearing language switcher, we advised the client to check the configuration in WPML > Language > Menu language switcher and ensure that the 'Menu' is set to 'Menu no countries'. We also suggested verifying that the navigation menu is assigned to the correct 'Display Location' in their website settings. Regarding the WP memory limit, we explained that increasing the limit is crucial to prevent potential crashes due to insufficient memory when the website grows and more scripts from plugins and themes are loaded.
