Background of the issue:
We need help with the 'Use directory for default language' feature on our site 隐藏链接. We have only one language, Spanish, and we want to use it as the default URL 隐藏链接. Additionally, we have detected a problem with some tables in the database related to WPML.
Symptoms:
The URL 隐藏链接 is returning a 500 error. There is also a database issue with the message 'MySQL server has gone away'.
Questions:
How can we resolve the 500 error when using the Spanish language as the default URL?
What steps should we take to fix the database issue related to WPML?
