When you have these type of problem - your safety is water changes. Do a 50% water change clean the filter media and restart the filter.
The beneficial bacteria not only reside in your filter but is present over all surfaces of the aerobic portion of the tank. By cleaning the filter media you will clear away any anaerobic decomposition residue.
The water changes will reduce the buildup of ammonia - plants too help reduce ammonia as they prefer the nitrogen in this form over any other. You will soon have the cycle back as before.
If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
