Is intelligence the "natural" product of evolution? The web server is trying to write latex related stuff into the images/tmp directory. dvipng GhostScript, ImageMagick and dvips can be replaced by dvipng.

Without them, and without the relevant environment variables, these executables may be unable to find their configuration, and you will get a relatively generic error.

You can check this by running: ls -Z texvc This will display a context like "unconfined_u:object_r:httpd_sys_content_t".
