Background of the issue:
I was trying to activate the sitepress-multilingual-cms plugin (version 4.7.6) on my WordPress site, but it caused a fatal error. I deactivated the plugin, and now I cannot activate it without encountering the same error. The issue can be seen on this page: enlace oculto.
Symptoms:
The plugin causes a fatal error when activated, and WordPress does not allow the plugin to be activated due to this error.
Questions:
How can I resolve the fatal error caused by the sitepress-multilingual-cms plugin?
What steps should I take to successfully activate the plugin without errors?
