Forum:Formulea copying difficulty

I've been trying to copy the Log-normal distribution article over from WP to the Psychology Wiki and keep getting this error message:


 * Warning: fopen(/images/wikitex/images/9/91/91c/aa46025433c145f780c88d1973abd) [function.fopen]: failed to open stream: Permission denied in /usr/wikia/source/wiki16svn/extensions/wikitex-1.0.3/wikitex.php on line 186

 * is it possible to get round this or do we not have the functionality?Dr Joe Kiff 12:52, 1 December 2006 (UTC)


 * It seems to be one specific tag failing:

$$\mathrm{var}(X) = (e^{\sigma^2} - 1) e^{2\mu + \sigma^2}.\,$$


 * If you change this very slightly, it works. For example, an extra space:

$$\mathrm{var}(X) = (e^{\sigma^2} - 1) e^{2\mu + \sigma^2}.\,$$

$$\mathrm{var}(X) = (e^{\sigma^2} - 1) e^{2\mu + \sigma^2}.\,$$


 * So probably just some random permission error (the name and location of the image is based on the MD5 sum of the text). --Splarka (talk) 22:05, 1 December 2006 (UTC)
