LaTeX screw-ups

Somehow this morning the renderer on WordPress decided to forget all of my backslashes in certain posts, with predictable results. I’m fixing them all back through the post on indefinite integration, but if you see any others earlier, send up a flag.

Incidentally, if you run into any LaTeX errors, particularly failures to render, please let me know in a comment on the offending page so I can fix them. It seems that every so often WordPress decides to play with those of us who use LaTeX, and I have to go back and fix all the mistakes they have introduced.

  1. It’s not just WordPress: PHP introduced a new escape sequence in version 5.2.5 and broke LaTeXrender.

    You know, for an invention which came out of CERN, the Web can be a really sucky place to discuss math and physics.

  2. I’m not sure that’s it, Blake. The backslashes aren’t being ignored, they’ve literally been removed from the code of some of my pages, but only those going back a few weeks it seems.

  3. This is seriously annoying! I am having the same problem now. So, the only way to fix it is by editing those posts manually?

  4. So it would seem. You get what you pay for with WordPress hosting.

  5. Today I had the same trouble but with the recent posts (in Portuguese) and not the order ones.
