Error with the last update

Dear WP Optimize Team,

I encountered an error with WP Optimize following the latest update, which led me to delete and reinstall the plugin. After doing so, I noticed that some features of my site are not functioning correctly, particularly when trying to open a new post. Disabling the cache seems to improve performance.

Could you please investigate this issue?

Thank you for your great work.
