Website Crashing

Hi SEOpress Support,

Before i installed SEOPress plugin, my website already has free YoastSEO plugin & is active and running. After i installed SEOPress, i changed my decision & deactivated SEOPress plugin.

Then started problem of below fatal error message. Also, none of my posts are visible & it has been throwing below fatal error in logfile.
So, To avoid issues of fatal error, i re-activated SEOPress plugin temporary & sending this message to you.

Now, could you tell me why SEOPress plugin throws fatal error when it is in deactivated state. could you please help to fix it??
