[url] tags have stopped working
The [ url ] tags no longer function properly: instead of turning a word into a link, it makes the word disappear completely. For example, see this post: http://www.mathisfunforum.com/viewtopic.php?id=24999
I have entered this:
Hi,
You might find this link useful: [url=https://www.mathsisfun.com/algebra/polynomials-multiplying.html]https://www.mathsisfun.com/algebra/polynomials-multiplying.html[/url]But the output has been this:
Hi,
You might find this link useful:Can we fix this? Any links appearing in any other post have also retroactively disappeared (take a look at this thread, for example: http://www.mathisfunforum.com/viewtopic.php?id=22506 ).

Re: [url] tags have stopped working
Eeek! Seems to be worse than that. I've checked out a few of my posts and not only have the urls gone but also the imgur links to images.

Re: [url] tags have stopped working
A function that used to work in PHP called 'create_function()' has been removed as it is a potential security risk. The forum uses that function to handle url tags and image tags.
I have found a work-around for the url tags, which seem to be working now. Yay.
Next I need to find a way to handle the image tags.

hi MathsIsFun
I've checked again and I'm seeing images again now. Thanks.
