Sometimes I just want to show some codes in my article,just like
Unfortunately,the "script" was always filtered after I clicked the save button every time.I thought it was the editor (tinymce) filtered it,but the codes were still filtered even I set the default editor to None in global configuration.
Finally I found the reason,the codes were filtered by Joomla for security reason,so how to get rid of the filtering?
Go to Article Manager and click the Options then switch to Text Filters.
There is a blacklist for every group by default,set the Filters Type to No Filtering instead of Black List then save.
