@juditnm Can you please try to disable other plugins keeping only WP-Optimize plugin active and check if you still see admin is loading slow?
We have experienced this problem. wordpress gets slower over time as the cache gets up.
After disabling the WP Optimize management bar, WordPress will run faster again.
Settings> General settings
Enable the cache menu in the admin bar
(This option adds a cache menu to the top management bar. Requires a page refresh after saving the settings.)
Good luck
@dagene010 Even if the WP-Optimizemanagement bar is enabled there should not be any speed issues, I’ll try to reproduce the issue at my end and report the same to our development team
Thank you very much Danny, you just saved me. I had 3 months with slowness problems derived from WP Optimize management bar and I did not know why. Everything was solved by disabling the bar. That bug has made me a lot of money.
