I am not sure if you had the chance to take a look at the documentation created by their team: hidden link
Also, please note that some known issues have not been resolved by their team yet (even though we reported them) and what you are experiencing might be related to those known issues: https://wpml.org/plugin/give-donation-plugin/
I hope that you will find this information helpful.
Thank you for contacting the support. I'm assigned this ticket and 'll try my best to help you resolve the issue.
Before proceeding further, may I ask you to fix and try the following please?
1) Fix “WP Memory Limit” to at least 128MB while 256MB is recommended. See https://wpml.org/home/minimum-requirements/ for detailed information. You can set this in your wp-config.php file by adding following code:
Remember to add these lines before the line where it says:
/* That's all, stop editing! Happy publishing. */
2) Then please turn off that option to "Look for strings..." and switch to a standard WordPress theme like 2021 or 2024, clear all caches and check again. Remember to take full backup of site and database before switching the theme.
Please let me know and I'll try my best to help you further on the matter.
