[SMARTCRAWL] issue with draft page

When SmartCrawl plugin is active I can't save draft correct, page just reload and page attirbutes, publish button are gone, screen option does not work.
When SmartCrawl is deactivate all works fine.

Duting the chat we:
- made full plugin/theme conflict
- increase max_execution_time and memory_limit
- enabled mbstring extension and restarted server
- reinstalled SmartCrawl (full delete)
- try to disable via php.ini file zlib.output_compression = Off

Nothing helps here.

Please check additional data from ticket and debug.log

Thank you
