Thanks, Alex
but nothing helps. The plugin was installed successfully. No PHP errors, no Wp errors. The problem is when I click Activate button, just waiting and do nothing until the server give me the page error (504 Gateway Time-out).
As o clue, I can tell you, the install works very good, I verified and I have all the folders and files in the wp-content and the rights ok but no tables in the db, yet. After click on Activate button, the plugin install just 2 tables in db, wp_t_questions and wp_t_schema_migrations and, finally, the server time out and the activation stopped
