Thread:Project:Support desk/Failed to parse (unknown error) when using the math extension

I have pretty much given up on troubleshooting this issue. I simply cannot get math/Latex to work. Here is the relevant information about my setup:

Operating system:

Fedora 20

Mediawiki version:

1.23.5

Database server:

MySql 5.6.21

PHP:

5.5.17 (apache2handler)

LocalSettings.php:

$wgEnableUploads = true; $wgUseImageMagick = true; $wgImageMagickConvertCommand = "/usr/bin/convert";

require_once("$IP/extensions/Math/Math.php"); $wgUseTeX =true; $wgUploadDirectory = "{$IP}/images"; $wgUploadPath ="{$wgScriptPath}/images"; $wgMathPath = "{$wgUploadPath/}math"; $wgMathDirectory = "{$wgUploadDirectory}/math";

$wgTmpDirectory = "{$wgUploadDirectory}/tmp"; $wgTexvc ="{$IP}/extensions/Math/math"; $wgDebugLogFile="{$IP}/images/tmp/logfile.log";

Troubleshooting already done:

-Did not forget to use php ./maintenance/update.php after changing my LocalSettings.php file.

-I have a tmp and math directory in /images. They have group owner "apache" with the appropriate permissions (775).

-I checked texvc by issuing this command in the terminal (with the appropriate directory names changed):

texvc /home/wiki/tmp /home/wiki/math "y=x+2" iso-8859-1 "rgb 1.0 1.0 1.0"

and everything is fine (the file is created in the math directory).

-I tried editing my page with SELinux turned off by using "setenforce 0" and I still get "unknown error" when using math.

-I've made every relevant .php and .php5 file executable with group owner set to "apache".

-I've check the Special:Version page and the math extension is correctly installed.

-Here is the log file that is generated after trying to access the wiki page:

Start command line script ./maintenance/update.php [caches] main: EmptyBagOStuff, message: SqlBagOStuff, parser: SqlBagOStuff [caches] LocalisationCache: using store LCStoreNull Fully initialised Connected to database 0 at localhost DatabaseBase::query: Writes done: UPDATE `page` SET page_random = RAND WHERE page_random = 0 SQL ERROR (ignored): Table 'my_wiki.profiling' doesn't exist (localhost)

-I tried placing the latex.fmt file in the /images/tmp directory and that still doesn't work.

Final comments:

I've followed every troubleshooting method that I could find through web search and nothing has worked. At this point, I have given up and I'm asking for some help.

Thank You
