I am having an issue with Views not saving at all on this site. I have recently updated Toolset plugins and now no View will save any changes - whether accessed directly or through Layouts. I have noticed strange issues with saving on a few other sites recently, but this is the first one of our sites that is refusing to save any data.
I have done the usual - disabled all plugins, switched to default theme - and even tried reinstalling all Toolset plugins, and it makes no difference. This site was running on PHP 7.1 and I've updated to 7.2 - still no change. I just get the endless spinning circle when I tried to make changes and update a View.
I have tried creating a test view, and that saves fine, but then when I try and make changes to it and re-save - the same problem arises.
