HTML not displaying after update

Because of the security patch in Nimble Builder, some HTML content type will now be more restricted. For example, due to WordPress requirements, it is not possible anymore to embed custom HTML code containing <iframe> tags in modules like Rich Text Editor module or HTML module. This type of content is typically added when users needs to embed small widgets displaying dynamic content on their page. The workaround is to now to use the HTML block of the Nimble Builder’s WordPress Widget module for this type of custom HTML snippets. See image:

@nikeo The only problem is with iframes? Any other content (e.g. images) will be Ok if update from 3.1.33 to 3.2.7?

I’ve reviewed all support tickets and did testing and iframe using rich text editor / html module is the only issue we are seeing. We had an issue with headings in 3.2.3-5 but that was repaired. Even given the iframe issue, there is a work around described previously. My recommendation is to backup your site and then update.

@nikeo Update with my experience…
My only concern was a huge post made with builder with tons of pictures, videos, iframes, shortcodes, rich text, html, etc…
Before update to 3.2.7 i followed your instructions and convert 2 iframes from rich text to widgets. Just updated and everything looks perfect.
Thank u!

@nikeo Thanks for the workaround. It was indeed iframes that were causing the issue and they’re now displaying using widgets instead. Is this likely to become an issue in future? ie. do I need to find an alternative to iframes to futureproof?

It’s hard to say definitively what could happen in the future, but we expect that we can use iframes using the widget without issue going forward.
