cannot create dvi formula

I ran into the same problem today. I have a PressBooks site with about a dozen technical webbooks, some of them have equations (rendered with WP QuickLaTeX). Everything has been working fine for over a year. However, when I added some additional pages, the equations in the new pages would not render, and I got the same error. Curiously, all the equations in the existing pages still rendered fine. (I assume they are cached.) I tried various workarounds but none worked until I deactivated WP QuickLaTex and then activated it again. That fixed the problem. You might give this a try. Good luck.

This issue is fixed now, please try.

Each formula is a small image file. Our server caches all the generated files for fast serving. With time, when number of images grow to few hundred thousands (or even million), Linux file system became overwhelmed and slow. This is the reason why QuickLaTeX “cannot create dvi file”. This happens very rarely, but still it happens.

In this situation, all the already generated formulas are working fine, but new one cannot be created.

Thank you for notification.

Thank you for your fast support.

It works very well now.

Again, thank you very much

Got the same problem today. Any new formula with \[ \] creates the error “cannot create dvi…”. Strangely, \( \) and $ $ work well. Existing formula do well, too, as long as I do not change them.

Unfortunately, deactivating and reactivating the plugin did not change anything.

Please help!

Please try now.
