@sstoqnov I have update our site with an new version of sgoptimizer and enabled it. It seems like the problem is fixed. Thank you so much.
Thank you. I will update our site tonight and let you know the result.
My site is running in siteground as well 🙁
Same issue as well. Admin console it’s available and browsing the website logged in as administrator is possible. As of now SG Optimizer is disabled to avoid “white screen of death”
