I successfully installed this extension and it is shown on the special:version page, however, im not sure if I am posting the actual spreadsheets correctly.
Currently I have it set as : "<spreadsheet sheet=0" file="/var/www/mediawiki/Excel/WIKITEST.xlsx"/>" the excel folder is something I created in the mediawiki folder but I am curious if there is a specific folder I should be putting the spreadsheets. Currently all I get is "file does not exist" any suggestions or assistance would be greatly appreciated
