 * Click [here](https://snipboard.io/43fnzd.jpg) to see the error I keep getting
   on the above page when I try to log in as admin. It has been happening consistently
   on a weekly basis for the last month.
    Here’s what a siteground support person
   said: **It looks like it is some kind of a plugin conflict between the SG optimizer
   and another plugin you might be having and one is blocking the functionality 
   of the SG optimizer which then causes the SG optimizer to break. I cannot say
   the exact specific reason or plugin causing this. But it seems it causes the 
   SG optimizer to freeze and flush its cache and only disabling the plugin and 
   reinstalling it does the job.**
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffatal-error-sg-optimiser%2F%3Foutput_format%3Dmd&locale=en_US)
