Problem:
The client experienced a noticeable slowdown and layout issues with Elementor after installing WPML. Elements such as headers and footers disappeared or appeared broken, and styles like text colors were affected. The issues were resolved upon deactivating WPML.
Solution:
We initially suggested a WPML reset and reinstallation, which did not resolve the issue. After further investigation, we identified the problem was related to the PHP settings on the hosting environment, specifically the

pcre.backtrack_limit

configuration. We applied a workaround by adding the following code to the

wp-config.php

file:

ini_set("pcre.backtrack_limit", 10000000);
ini_set("pcre.jit", 1);

This code increases the

pcre.backtrack_limit

and enables

pcre.jit

, which resolved the issue. More information about

pcre.backtrack_limit

can be found here.
