Problem:
You are experiencing PHP fatal errors related to memory exhaustion on your website after upgrading to WPML. The errors occur inconsistently across different pages but only in the original language. Despite increasing the memory limit, the issue persists, suggesting a potential loop causing the memory exhaustion.
Solution:
First, try the following steps:
1. Navigate to WPML → Languages.
2. Locate the option **"Adjust IDs for multilingual functionality"** and disable it.
3. Save the changes to apply them.
If the problem continues, implement this code snippet to modify the behavior of the Hummingbird plugin's persistent cache:

This code removes the 'terms' group from the cache, which might be contributing to the memory exhaustion.

If these solutions do not resolve the issue or seem outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket at WPML support forum for further assistance.
