Yes, I have tried indexing the data by resetting the database tables and the process does not finish, just like when I hit it without resetting data.
I did that the first time it did not finish optimizing.
There are no javascript errors, there is only a warning with yellow background, something about the non-standard “zoom” property. Optimization bar get stuck when it is full, and the error message by YOAST plugin doesn’t appear, it only appears when I press any link to exit that section, so it appears during 1 second and I can’t press the little arrow to expand and see the error message. I think I was able to see it one time going back on my browser, now I can’t see it because the page reloads completely so optimization button appears again.
