 * Hi …
 * I just found the error “cannot create dvi file” when I want to render latex.
   
   I have search the similar problem on your site [http://www.holoborodko.com/pavel/quicklatex/](http://www.holoborodko.com/pavel/quicklatex/),
   you said that to let you know for this kind of problem. I have tried in quicklatex.

 * 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.

 * 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!
