This thread is resolved. Here is a description of the problem and solution.
Problem: The client is experiencing PHP warnings related to the
simplexml_load_string()
function in the WPML plugin's class-wpml-tm-xliff-reader.php file. These warnings include parser errors such as 'Opening and ending tag mismatch' and 'Sequence "]]>" not allowed in content'. Solution: We recommended the following steps: 1. Increase the WordPress memory limit to at least 128MB, as per our minimum requirements. This can be done by adding the following line to the wp-config.php file:
Place it above the line /* That's all, stop editing! Happy blogging. */. 2. For issues related to product author and attributes, follow the steps described in our guide on how to correctly import taxonomies and their translations. You can find the guide here: https://wpml.org/documentation/related-projects/wpml-export-and-import/
