I have a problem from the last wordpress update 4.9.6. Editor in sections on the pages is blank. Data is there, but i can not edit data or see data, everything is blank. Website live is ok, sections are there, everything is there, but i can not see or edit sections.
Now it showed up. Very strange. I had that problem a year ago, and also it showed up tomorrow. Now, disappeared a couple hours ago, then showed up, and again disappeared and now showed up. I dont understand. I will inform you if i have the same problem. I will send you login details in that case.
Most definitely caching related. First I tried with another browser – worked. Then went back to my main browser and tried cleaning up specific cookies, no luck. Did a full cleanup on my main browser and saw the content again.
