Product configuration page goes into "saving" loop after selecting any module

[SGCH]

Hello!

 

After either creating a new product and selecting a module or going to an old product and editing it - the configuration page goes into a "saving" loops every second. This issue has started roughly sometime within the last week and I am unsure if it was before or after updating to 5.3.9 since the last time we went to create or a new product was the same day of the update. Initially I thought it was an issue with ModulesGarden addons that we use - but after disabling them and trying other available modules we discovered it happens with every last one of them!

 

I checked all of the logs within WHMCS and I only found errors related to DNS changes a customer was making while I was debugging the issue - nothing else appeared.

 

Any ideas would be appreciated.

 

Thanks!
