Likely causes
Overwatering
Most likelyHow to tell: The soil remains soggy and the base of the stems may turn black or soft.
What to do: Stop watering immediately and let the soil dry out completely. If the rot is advanced, repot the plant into fresh, well draining soil after trimming away the black, mushy roots.
Poor Drainage
Most likelyHow to tell: Water pools at the bottom of the pot or the soil stays saturated for more than a week.
What to do: Ensure your pot has drainage holes at the bottom. Use a potting mix amended with perlite to improve aeration.

When to worry
If the roots are slimy and falling apart, the plant is in critical condition. It is normal for a few roots to be brown if the plant is very old, but they should still feel firm.
Stopping it coming back
Only water when the top inch of soil is dry and never let the plant sit in a saucer of standing water.
