I apologize for the vagueness of the question, but was looking for tips to debug more than a solution. I am using EE 2.7.2. I have a channel called products and a channel called resources. Within products there are two relationship fields (built-in relationship fields, not using an add on for it), one relating other products and another relating resources. Everything works as planned, but on multiple occasions (three times now) one of the relationship fields gets cleared for some of the product entries.
For example, Product A is related to Products B and C and Resources A, B, and C. It will all work then while reviewing the site (usually a week or so later) Product A will only be related to Resources A, B, and C and not related to any Products, as if they had been cleared.
Again I apologize for a lack of details but am totally stumped and not even sure where to start or what details to include? I have been grabbing a back up of the exp_relationships table each time it happens (before and after re-entering the relationships) and it appears that those rows are just getting removed for one of the relationship fields (it was the resource relationship twice and the product relationship once). There doesn't seem to be any action that triggers this or even a set timeframe, so I have very little to go on. One thing to note is that there is a channel form tag for another channel that also has a relationship field for Products. I tested this out thoroughly and it didn't seem to trigger the problem. I was hoping maybe someone else had experienced this or has some ideas of what to look for? Thanks!
