I am using LR 5.6 and quite happy with it (yet to upload v.5.7.1) and I must have hit a wrong button somewhere because all info in the Develop module , with the exception of the Histogram, is now missing.
Here are two screenshots I took. I cannot proceed with any further post processing. Please help.
In Develop mode, do Window > Panels > Basic, Window > Panels > Tone Curve, etc. to re-show all the missing develop panels.
Wow. Thanks a million John. It worked!
