After doing all the work, I clicked save on Cornerstone and nothing was saved. If I change anything again, the Save button will have a red round No sign that won’t allow me to click to save. If I click Crtl+S it displays the hooray messages or whatever but the page is not saved. I tried with Chrome and Firefox and both have same behaviour. Frustrating when you work so hard on the page to notice that Cornerstone is not saving anything. how to fix this?
Note: Yes I have all the mem stuff increased at max as per your recommendation.
