Thank you for contacting WPML Support, I will gladly help you.
I noticed from the debug info you provided that you are using:
- WordPress v6.3
- WPML 4.6.6
I suggest you first update to the latest version of WordPress (v6.4.3) and WPML (v4.6.9) (also update the WPML addon plugins).
Also, It might not be related to the issue, but according to your debug.info, the WP memory limit needs to be increased, WordPress uses 40Mb as default and the minimum requirements for WPML are 128 MB. (Kindly check this page: https://wpml.org/home/minimum-requirements/)
You can increase it by adding the following code in your wp-config.php file right before the line: /* That's all, stop editing! Happy publishing. */
1) Could you please try removing the key "wpml_string_table_ok_for_mo_import" from the options table (by default wp_options, where "wp_" is your database prefix)?
2) Check your database after this, if all icl_string tables are there:
