Problem:
Unexpected Server load from wp_icl_string_pages
Solution:
a) Upgrade to the latest version of WPML
b) Visit WPML>>Support>>Troubleshooting page, then click on *Recreate ST DB cache tables* button. This will clear the String Translation caches, including the *wp_icl_string_pages* table.
c) Visit WPML>>String Translation and enable *Auto-Registering* option for all the String Domains.
Problem: I want to translate WP Front Notification popup and buttons/links
Solution: currently, WP Front Notification isn't fully compatible with WPML but you can tweak the code to translate the popup and the buttons. See the 2 links below, in the first one you can find instruction for the popup, in the second for the buttons
