OK, will look at both of those.

Hi MIF

It seems the plus problem is very persistent: http://www.mathisfunforum.com/viewtopic … 26#p253826

Yep you are right.

To speed up page loads, once latex is created it is kept in a large cache. If latex was always being created things would be really slow.

So if you write some latex that has already been done you get that old version.

Try changing it a little (say with a space or variable change) and it will likely have to make a new one that works properly.

So, the cache has the LaTeX version of that expression from before you fixed the plus problem?

Yes, and I can delete it manually, by looking up its cached name. Such as "f/f/29156445d5e534d194b44703db36ab1.gif" for the misbehaved image above.

A workaround would be to escape it:
