[23:19:04] <Guest7062>	 Hi, I'm trying to debug Failed to parse (PNG conversion failed; check for correct installation of latex, dvips, gs, and convert): P = \frac{U}{t}\. I found that the texvc command is run correctly in Math.php and produces a valid output with the correct hash and HTML. But this is not saved in the specified tmp directory. Neither the .tex nor the
[23:19:05] <Guest7062>	 .png is saved.
[23:20:23] <Guest7062>	 The texvc command generated inside Math.php seems to be correct. When I run that command from the command line it does generate a PNG in the specified tmp folder. But somehow when executing via the web it is not working.
[23:25:26] <Guest7062>	 Command is ./math/texvc '/var/www/tmp' '/var/www/tmp' 'P = \frac{U}{t}\,' 'UTF-8' It does not produce the expected PNG file in /var/www/tmp. But when I run that command either as my user or after sudoing as www-data, it does work. So it seems that the underlying dependencies are all working correctly.
