I'm using BreezingForms since years without problems. I don't know exactly since when, but now I have problems with my sitemap (OSMap): it can't be rendered and a "404 - No form id or name provided!" is been displayed. If I deactivate the BreezingForms content plugin the sitemap works. If I use Iframes in BF plugin the sitemap works. But Iframes are not a solution! The forms look terrible on Iframes.
So can you please check where the problem comes from?
No, OSMap has an own plugin group, so I cannot change the order.
I already contacted OSMap support and they said, the problem is BreezingForms... I don't know which one introduced the bug, it was working some versions ago (both components are up-to-date).
So maybe will be good if BreezingForms talk to OSMap and together try to solve the problem
Sorry, but what they are saying isn't true. Their code is executed first, before the BF plugin is even triggered. If they make such a claim, they should at least say why they think BF should be the culprit and not just trying to get a support case out of their way.
The content plugin does nothing else than parsing the article content for the tag and displaying the form based on that.
However, I ask you to contact them again because their code is executed first, obviously interfering with the content plugin workflow. As you can see in your screenshot, if you read bottom up, you can see that there is a lot going on and I am not willing to debug someone else's extension.
From the error message itself I can only guess at this point but it seems OSMap unsets the "ff_name" request parameter. At least this is the reason why the error has been thrown (simply doesn't exist anymore after the OSMap code has been executed).
...follow up: also please make sure to install the latest version of the content plugin located in the main download package (/extensions/addons/plg_breezingforms.zip)). Just install it over the existing.
