Ok this is an obscure issue. I have a long standing complex Joomla site that uses the forms package in many K2 articles buried in a tab. After a lot of de-bugging I have found out what got broken on the last update.
My problem was that a whole set of k2 categories would not load and went to the redirected Joomla 404 page. The individual articles opened fine and the forms in those articles opened fine. The problem has been difficult to diagnose becasue immediately the URL hits the Joomla core it gets rejected and I don't get to see any error log or trap anything.
I slowly backed out of the upgrade and determined it was an issue in the com_breezingforms update. I narrowed it down to the new breezingforms.php in version 1.9.1.stable (937) the previous version I have 1.9.0 (935) works fine. So, unethical it might be, but just changing that file causes the site to fail, but all the forms still work fine and I see no issues other than a whole set of categories fail to load. The file has the same version and header but when I diff the file I see there are some changes to the code.
So, my question of the developer. Any pointers to look for, you probably know what you changed in that file and perhaps have a clue as to why the forms package fails to work in article promos loaded into a k2 category. The forms are added using the plugin which is placed in side of coded tabs. The menu item that fails is a k2 category pulling up a single category. It is a custom layout with extra fields, one of those extra fields has the breezing_forms trigger for the plugin to display a form. The format of the URL is index.php?option=com_k2&view=itemlist&layout=category&task=category&id=163
I don't get as far as running the Joomla debug consol, just the title. But I do get a little info in the error log:

If I back down to php 7.1 then I get nothing in the error log but still have the issue.
Basically I have no more paths to try for debug and solution, hence this request. Just give me something to check or pointer to see what might be causing the issue?
